That's great news. From April onwards buying from a reliable vendor with fulfillment by Amazon will mean you get the parts from that vendor, not some random parts from a random provider that claim to have the same SKU.

Seems like Amazon finally agrees that the counterfeiting issues from commingling are worse than the logistics advantages

> Seems like Amazon finally agrees that the counterfeiting issues from commingling are worse than the logistics advantages.

The cynical perspective is that they are facing a serious financial penalty either from the manufacturers themselves, or a large buyer that got burned by co-mingled products, or both.

indymike•1h ago
I suspect this one is death by 1000 cuts as Amazon has distribution facilities everywhere and will be subject to state and even local laws concerning warranty, product safety, and trademark. You can't contract your way out of it, and defective and counterfeit product can even carry criminal liability depending on jurisdiction. Good move Amazon.

While high value resale brands like Apple and GPU manufacturers would be the obvious choice here, I’d be tickled if it was LEGO Group that finally forced their hand, given how many stories there are of people receiving faked parts, missing mini figs and straight up bags of pasta.

ninkendo•32m ago
That wouldn’t be cynical at all! It would mean that the system works, albeit slowly.

The best we can hope for is a world where Amazon faces real financial pressure to prevent counterfeits. Thus far I haven’t seen much evidence this was happening, but this is a welcome sign.

groundzeros2015•6m ago
Of course. Businesses only change when you complain and vote with your money.

That’s not cynical, that’s the system working. And if you keep bringing your money, you are signaling it’s a little annoying but not it’s ultimately ok.

Noaidi•1h ago
Great news? It’s great news that nobody really knew that we were buying items but not receiving them from the person that we bought them from? It’s a logistical advantage to defraud customers? Because this is what Amazon was doing all along, defrauding customers. I never knew that I was receiving an item from someone who I didn’t purchase it from how is that even legal?
wongarsu•59m ago
Amazon's assumption was that every box of "Apple AirPods 4" is the same, so it doesn't matter if you got the one sold directly from Apple or from some random reseller. They would just put them in the same bin, after all they are all the same product. Great for logistics because it doesn't matter if the closest fulfillment center has AirPods sold by Apple or "Office Partner Inc", they just ship you whatever is closest. Obviously this fails spectacularly if a seller ever lies about their product, but who would ever do such a thing
lazide•31m ago
It also fails when someone receives the product, and then returns it (bonus points if it was ‘not what I ordered/fraud’) with the contents replaced with something bogus, if Amazon puts it back in stock.

I know they do sometimes put it back in stock, because the item I received back (as the ‘we’ll ship you a replacement) was literally the same thing I shipped back to them. :s

prewett•38m ago
It's been discussed a number of times on HN. The Wall Street Journal even had an article about counterfeits on Amazon a few years ago. There's one at [1] (paywall, naturally).

I'm not sure if it is fraud, but it definitely aided and abetting counterfeiters, and I think it is a travesty that Amazon has not been fined for it. I also actively avoid buying from Amazon partly because of this (and this decision will make no difference; I have no interest in patronizing a company that does this, unless I see some repentance), although there really isn't anyone else for a lot of items.

I bought an LG monitor, by part number, three times and always received the similar looking but half the price counterpart.

We only realized the issue after using it for a few days and needing to use an advance feature.

So, it’s not just one sellers product mingled with another, but also sellers combining similar looking products together as well.

numpad0•25m ago
Amazon apparently credit full declared cost for the seller who delivered items to be comingled, and all responsibilities for the item are offloaded to whoever seller that would appear on customer invoices.

This means malicious sellers can deliver literal counterfeits to warehouses and externalize the consequences, down to angry 1-star reviews and disposal of returned counterfeit examples, to somebody else.

You don't want to risk damaging an expensive phone/laptop/TV by plugging in the absolute cheapest unbranded cables/adaptors etc if there's a trustworthy brand available.

And with some electrical stuff, such as power strips and chargers, there might be safety issues/fire hazards too.

mikkupikku•1h ago
Why now, and not 15 years ago when their reputation started tanking for this reason? And when are they going to ban the re-use of listings for unrelated products?
shevy-java•1h ago
Their reputation actually dropped for many more reasons.

Prime was one reason - I always hated it and I felt that when Prime came out, the general service elsewhere declined. I could not accept to be a second class citizen now. Either I'd have to also use Prime - or stop using Amazon. I opted for the latter.

But there were also more complaints that people made online, which was different before Prime. The opinion of others does influence me a little bit; I try to not let it influence me, but truthfully when there are many negative comments, one becomes suspicious too. Perhaps one reason Google disabled downvotes on videos, as this was a quality control step by some users, which helped a bit; I would not waste my time on horrible videos. And for the most part, users voting was working ok-ish.

kop316•1h ago
Agreed. Doing something about this should have been well over a decade ago, not now. Considering how long it took, this isn't going to bring me back from ordering from Amazon.

Nobody stops you from buying products directly from the company's website. You don't have to buy everything from Amazon.

I browse on Amazon, and then go to the company's website directly for the purchase. USPS, UPS, and FedEx will still deliver it just the same.

mark-r•1h ago
But not same-day. But even that's a bit iffy - I made a purchase from Amazon recently where they promised same-day delivery, on a Sunday no less! But it didn't actually arrive until Wednesday.

TIL To keep the price of Kenyan coffee low, the British set up markets and ratings. All the beans are commingled. Plus added bureaucracy. So no farmer would be directly incentivized to excel. Just a race to the bottom.

Insidious.

It perfectly described what Bezos did.

Sorry, I can't quickly find the article explaining the unique history of Kenyan coffee. Will add later if I do.

This org's page hits all the same points:

Kenya Coffee, Quality Decline & the Systemic Truth Behind the Cup https://kenyacoffeeschool.golearn.co.ke/kenya-coffee-quality...

The article I read was written by a (western) coffee buyer explaining why he can't buy beans directly from Kenyan farmers. Whereas buyers can directly in every other country.

u/jrjeksjd8d found it. Woot!

Angostura•1h ago
If there were ratings, presumably the incentive would be to have your beans rated as higher quality.

Thus doesn’t feel particularly evil to me - though it treats beans as fungible.

Something similar is done with milk sales from individual farms in England.

jrjeksjd8d•1h ago
This is the original source, linked on HN a couple months ago: https://christopherferan.com/2021/12/25/kenya-and-the-declin...

It seems like the collective washing and grading system was effective at producing high quality coffee (but not paying farmers a living wage) until the system got so extractive and climate change got so bad that farmers cut costs and started producing worse strains. In other markets buyers would go direct to the farmers for single-origin beans to encourage higher quality but in Kenya this was prohibited.

DoughnutHole•1h ago
Not particular unique - this is a common practice in a lot of agricultural industries. e.g. there are wine co-ops in France where many vineyards commingle their grapes to produce a commercial volume of wine under a particular label.

What these systems rely on is a governing body that punishes producers that don’t meet the body’s standards and ruin the party for everyone else. Amazon is the governing body here and has previously shown no interest in protecting legitimate producers from counterfeiters.

Personally funny example to me, because, at our anti-counterfeiting tech startup, 3M respirators was the prospective customer I championed.

Why wait so long? Do it now…

This is the same company who creates internal systems that encourage wringing out every drop of effort no matter how many piss bottles litter their work environment. When a faceless program uses gamification and comparison estimations to keep their employed serfs always working, constantly fed a sense of being behind. The stress of it all without the minimal of a “good job!”

You’re telling me THAT style of company isn’t capable of achieving this goal for another 2 months? If the company is going to use reprehensible practices at least use it to achieve good quicker.

To me this feels like releasing a press announcement to generate good PR and waiting until everyone forgets before not actually doing the thing… That’s my cynical take.

mrweasel•1h ago
That fact that they ever did this is kinda crazy. Did they not imagine that someone would try to sell counterfeit products? Commingling means that a seller could be hit by a refund and bad review for a product that was never theirs.

It's about time! They never should have allowed 3rd-party sellers on the platform until this was in place.

myself248•59m ago
> They never should have allowed 3rd-party sellers on the platform until this was in place.

Exactly. From the modern perspective, it's a function purpose-built to abet counterfeiters.

However, look at their origins as a used book seller. When my sister went off to college, I got most of her books off Amazon for a third the price of the university bookstore, and they were all from third-party sellers promising they had a particular edition and printing of a given book. All the same ISBN regardless of where they came from. It made sense in that context, to consider all sources of a given item to be the same item.

However, at that time (2005), all the books shipped from their individual sellers, there was no opportunity for stock commingling. If one had turned up counterfeit, blame would've been trivial.

So I don't think "3rd-party sellers" is necessarily the cutoff point. I don't think they should've allowed multiple suppliers for the same ASIN to all have their stock *in Amazon warehouses* until individual supplier tracking was in place.

Loughla•31m ago
Just on a related note for anyone in college in this thread. Forgo the book fees or technology fees or whatever bullshit they wrap up in your tuition and go to dealoz.com. Buy the books you want to keep and rent the ones you don't. Save yourself.

al_borland•1h ago
It’s about time. I’ve been going out of my way to not buy from Amazon, especially on items that are often counterfeit, or where a counterfeit item would cause real issues.

Just a couple days ago I was planning to buy some supplements, which Amazon had. I went to the actual website of the company and bought from them, because the idea of getting a knock off was a bit scary. To my dismay, I received an Amazon shipping notice after making the purchase outside of Amazon. This brought back my skepticism. I’m still waiting for the package to arrive and will end up inspecting it closely.

A few months ago I bought some headphones from Amazon, because the official site was out of stock on the color I wanted. I ended up going on YouTube and finding a video on how to spot authentic pairs vs counterfeit ones to make sure I got the real thing.

This all stemmed from when I bought a water bottle, and the reviews mentioned this commingling issue and how to spot authentic real one vs a fake. I double checked that I was buying from the company’s listing and not one of the other sellers on the item. I received a counterfeit one. Thankfully this review tipped me off. I lost a significant amount of trust in Amazon that day. A random bottle isn’t something I even thought I needed to worry about counterfeit version for.

Amazon has a long way to go to rebuild trust with me. This is a step in the right direction. The fact that it took this long is pretty sad. Amazon is the only mainstream store where I’ve ever had to question if I was buying legitimate goods or not.

antonymoose•1h ago
Another counterfeit issue they have that will not be solved by this is the “REPLACEMENT PART FOR OEM FOOBAR-123” listings.

I’ve had quite a few repairs over the last few years for household appliances and pool pumps and such. It’s very common to find a listing for a heating element for a Samsung dryer or a Heyward filter diverter being listed with a misleading title and often further listing the manufacturer as, say, Samsung itself.

I got screwed after buying a dryer heating element for $80 recommended via a reputable YouTube DIY channel. Silly me neglected to check the comments and lo and behold 50%+ are complaints that this heating element dies after 6-8 weeks, just past the 30 day refund window…

nmcfarl•29m ago
This is not always a bad thing. The example I always use of why it’s good that Amazon has knock off parts, is a Jacuzzi heating element.

Amazon has them for $30, but has none of the legitimate item which are only sold through a dealer network and dealers charge the OEM price of $285 bucks plus shipping. It’s not quite the same part – cause dealers only sell a larger unit that includes the heater - you can’t buy the actual part number except via a knockoff.

Add to this that the Jacuzzi part - for my model at least - has a reputation of just dying at two years plus one day, while the Chinese parts frequently last 3-5 years.

In the end, you save yourself quite a lot of money, and time by replacing less frequently, by buying the knock off. And where I live, you couldn’t get the knock off otherwise.

The important thing of course is to know that you’re getting a knock off, and have made that choice in intentionally. Your story does suck - and there can be lots of reasons both good and bad to make a knock off.

retSava•25m ago
This is one of many exploitative habits of Amazon. Others include not ensuring products follow regulation, eg on hazardous substances (lead, etc), or on electrical safety. They also make your local {book, game, hobby, ...} shop go bankrupt.

You don't -have- to buy there, if you have the financial means I urge/recommend/encourage you to buy locally or from a responsible seller. Even if they are slower, less things on offer, etc. You probably already know some small local stores you would be sad to see shut down. Support them! (if you don't already)

mikepurvis•8m ago
> follow regulation

This one bit me recently when I bought a package of budget light fixtures (in Canada, from amazon.ca) and then my licensed electrician informed me that he wouldn't be able to install them as they didn't have a CE mark.

To their credit, Amazon did allow me to return them without penalty, and now my review there warns other consumers that those are only for DIY use and even then you are risking your home's insurance coverage.

embedding-shape•6m ago

Actually make sure with a incognito window that this review is actually visible. I've noticed that some reviews of mine have been "shadow-banned" and while it looks like they're still there when I'm logged in, once I try in a incognito window the review doesn't show up publicly anymore. My reviews were just basically facts about the products themselves, and received no word from Amazon about breaking any rules.

The text in that attached screenshot is the key giveaway, "Now that most sellers maintain inventory levels that keep products close to customers..."

This looks like a signal that Amazon's fulfillment network has reached a saturation point where the 'distributed cache' model of commingling is no longer necessary for speed. Ten years ago, commingling was a necessary optimization. If seller A (county A) and seller B (county B) both sold the same widget, Amazon treated them as a single distributed liquidity pool to guarantee 2-day prime shipping nationwide without forcing every small seller to split their stock across 10 warehouses.

Now that Amazon has moved to a highly regionalized fulfillment model (where they aggressively penalize sellers who don't have stock distributed across regions), the computational and reputational overhead of commingling outweighs the diminishing returns on shipping speed. For all intents and purposes, they have traded the operational complexity of physical sorting for the software complexity of forcing sellers to manage regional inventory better.

Also total warehouse capacity and warehouse-warehouse freight capacity. +X% inventory duplication (to achieve regional inventory) at Amazon-scale, along a long tail distribution of products, must be non-negligible.

aserafini•48m ago
My recollection (admittedly worked for Amazon >19 years ago) is that there was never any computational overhead to commingling. In fact, the opposite was true: there was a computational overhead to tracking which vendor a specific piece of inventory of a given product came from instead of assuming that all inventory of that product was fungible.

This affected returns as well. For multi-sourced products, we could never guarantee that overstock or damaged items were returned to the original supplier—only that the product matched. Suppliers complained about this a lot.

withinboredom•33m ago
Worked with a guy that used this to his advantage. He sold CD's and DVD's through FBA. He would get them "new enough" looking via buffing them out (often making them unplayable), shrinkwrapping them, and then hope whomever got them wasn't him that got the commission for that sale and instead the person who bought "from him" got one of the actual new ones. He made a killing off of this since "used" inventory was incredibly cheap for a whole pallet of them.

By "used this to his advantage", it sounds like he was just a fraudster?
xnorswap•24m ago
Does this story have a happy ending such as a conviction for fraud?
ajkjk•11m ago
There was some overhead to commingling once it got extended to FBA, because in order to increase commingling they did attempt to track inventory provenance information even on commingled inventory.

My first job out of college in 2013 was working at Amazon on one of the teams that was implementing inventory commingling at the warehouse level, and my first big project was implementing this process into the receiving software, which is when inventory arrives at warehouses from vendor/seller trucks and employees scan everything to make database records that lead to paying for the goods. Note: in Amazon lingo "vendor" means a provider of goods that are legally purchased and owned by Amazon in the warehouse, while "sellers" are FBA sellers that maintain ownership of their goods and basically rent Amazon's warehouse services.

The big software undertaking was determining, at inventory receive time, whether we trusted the seller enough to allow their inventory to be commingled with others. If yes we would be "virtually track" the provenance: store in the database a record of the vendor, but if the item became commingled (according to UPC scans as it moves around the warehouse) with other sellers' inventory, blur the information so as to not falsely attribute provenance when it was no longer known. The whole project was based off the cost:benefit analysis that the efficiency and customer experience benefits outweighed the cost of not being able to attribute damage to the correct vendors (particularly the fact that you could ship a customer a product from the closest warehouse that it had it, instead of transshipping it from the warehouse that had the one owned by the person they bought it from).

In cases where sellers were not trusted enough to commingle there were alternate processes that were supposed to track their items individually; the most granular was "LPN" receive, license-plate-number, where every product got an individual UPC to distinguish it from all others. This was borrowed from Zappos, whose one warehouse in Vegas was initially the only one who used this process; I was told that was because the online shoe business heavily relied on letting customers do loads of returns and so it was implemented out of necessity early on. One of our projects was rolling LPN out to more of the North American network. But it was a lot more expensive (in the stickers, labor, data management, and picking inefficiency) so it was dispreferred whenever possible.

At the time the whole commingling initiative was regarded to be a big win for both Amazon and customers. It was fairly janky from the beginning, though, and I'm not at all surprised that sellers (and to a lesser extent vendors) began taking advantage of it as soon as they began to realize how it worked. There were a lot of initiatives around the time I left to provide better accountability in the whole process, but it is ultimately an arms race between Amazon and the merchants and my impression is that for many years Amazon was losing.

It is amusing that they're ending it. I never heard how things were going after I left, but had the impression externally that it was ending up being a disaster, and knowing how it works on the inside it's not a surprise. In hindsight trusting FBA sellers to not become essentially malevolent actors seems comically naive.

I wonder if the meteoric rise in people using LLMs for advice had anything to do with this?

I was recently using ChatGPT and Perplexity to try to figure out some hardware glitches. I've found LLMs are way better than me at finding relevant threads for this kind of problem on Reddit, company support forums, forums of tech sites like Tom's Hardware, and similar.

The most common cause of the glitch I was seeing was a marginal Thunderbolt cable. A Best Buy 15 minutes from me had a 1m Apple Thunderbolt 5 cable. Amazon had the same cable for the same price with overnight Prime delivery.

If I'm spending $70 for an Apple cable I want it to actually be an Apple cable, so I asked ChatGPT if an Apple cable sold by Amazon was sure to be a genuine Apple cable.

It told me that it likely would be, but if I wanted to be sure buy it from Best Buy.

I bought from Best Buy.

speedster217•55m ago
I've made that decision before without the help of LLMs so I'm not sure what you're trying to say here. It feels vaguely insulting to our intelligence.
tzs•4m ago
I've made that decision before without LLMs too. If I had been Googling to find possibly relevant material instead of using LLMs to find possibly relevant material, I probably would have bought from Amazon.

With Googling the "figure out what is going wrong" part of solving the problem is more decoupled from the "figure out where to buy this thing" part. The first part involves Googling, looking at a bunch of results, finding a lot are not relevant, trying to refine the search, and repeating probably many times. After that time consuming process when I have finally decided that I needed a new cable I'd probably just go to Amazon without thinking about it.

I always have a little doubt when buying from Amazon because of commingling, but usually not enough to look deeper into it unless the product is something with a high risk of it.

With the LLM instead of Google I upfront described to it a lot of details of my equipment, how I was using it, what symptoms I was seeing, what diagnostic steps I'd taken and the results of those, and why I believe certain things that could cause such problems would not be applicable in my case.

It then finds all the stuff I would have found by Googling, but because it also has way more information from what I told it at the start it can eliminate a whole bunch of the irrelevant results, so I'm starting out way ahead of where I would be after a first Google. A little back and forth and I know what I need to buy.

At that point I'm still at the LLM screen. Since it is right there tossing in a final question about buying from Amazon vs Best Buy is trivial.

I'm not a frequent LLM user. I have yet to pay for any LLM. (I did have a year of free Perplexity Pro that Xfinity gave to its customers a little over a year ago, but when that expired I did not subscribe.

(There's a funny story there--when it expired and they tried to convince me to subscribe, I asked Perplexity if a subscription would be worth it. It told me that considering my usage patterns the free plan was perfectly fine for me and I should stick with that).

A lot of people now are using LLMs instead of or before traditional Google-style searches when they want information. Not just techies or early adopters. The are or are quickly becoming mainstream.

If they are recommending not buying from Amazon that might be something Amazon would want to address.

Gopro subreddit daily has people posting issues with their camera complaining about the SD card. In all instances they've bought a "genuine" card on Amazon from the official seller, but probably received a fake one due to commingling.

The brand hit from this must be massive, with the amount of people now avoiding Amazon. But perhaps it won't matter with their size, most people won't have any other options anyways. For me, it was counterfeit dental stuff that made me quit buying from Amazon. A faulty SD card is annoying, stuff I put in my body is no-go.

Now that they’ve effectively destroyed their competition through predatory pricing and services, the ensh*ttification can accelerate.

This holiday season, I wouldn’t buy high priced high quality items from Amazon due to concerns about counterfeit. I probably still won’t even after they’ve made this change. DTC from quality producers now have decent websites, free shipping, and good customer service. If I’m going to buy a premium expensive product, why risk it.

A friend that used to be high up at Amazon fulfillment told me inventory commingling was the reason he was unwilling to buy anything from Amazon to put in or on his body. Huge indictment for the brand and clearly a bad long-term strategy in the age of fake internet everything.

This will hopefully be a huge improvement for the reduction of fraud on the platform. Hopefully, they give the ability to only buy from verified vendors. This is why only buy CPGs on Walmart.

I've rarely experienced issues, Amazon has always been happy to correct any issues, and I strongly suspect prices are going to jump significantly. I can't find any other notes of skepticism and I'm heavily doubting as I write these words, but it's surprising to me how much scorn and disdain people have for commingling.

It's wild to me that everyone's happy product makers have full price control now.

> you could order from a good seller but get counterfeit products sent in by a shady one, and Amazon wouldn't even tell you

Why does the word 'monopoly' come to mind?

This is great. I do wonder if eventually we’ll see brand names return. I basically only order things that I don’t care about quality with now. It feels like Temu.

This is one of those things that's an amazing idea in a perfect world with no fraud or bad actors.

From the article it says the change is implemented by telling brands they don’t need an amazon barcode if they have a product barcode, while resellers need an amazon barcode. What happens if resellers decide to just not add the amazon barcode and appear as brands?
