Amazing they weren't prosecuted for it.
Someone1234•2h ago
Yeah, "shipped and sold by Amazon.com" was essentially selling and shipping millions of dollars of fully counterfeit products under this program for years. If a small vendor does something like this, they'd have the fed kicking down their door after tens of thousands.

I personally received counterfeit and tampered products "shipped and sold by Amazon.com" on half a dozen occasions. Even as recently as the last two months.

Was this a lie or did it change?

I had always thought they must be the biggest distributor of counterfeit products in the history of the country.

It was one of those things that I couldn’t explain, and just wrote off before it broke my brain.

dataflow•2h ago
> During Wednesday’s presentation in Seattle, Amazon executives said the economics of commingling no longer worked. With the company’s logistics network now capable of storing products closer to customers, the speed advantage of pooled inventory has diminished.

Sounds more like they were losing market to other retailers.

redserk•2h ago
I don’t think I’ve had a counterfeit good come in, but the number of times I’ve heard about it led me to start going to other retailers for things I wanted guarantees on: cleaning products, personal hygiene items, and expensive electronics/accessories.

Amusingly after that, I saw I could get nearly everything else off AliExpress for cheaper. My usage of Amazon practically evaporated.

freshtake•1h ago
This. Amazon buyer metrics have been tanking for a while. In general if I don't care about the quality I have better and cheaper places to shop. When I know the brand I want, and want predictable quality, I order from the company directly. Price, service, quality, and delivery time are equal or better than Amazon.
icelancer•1h ago
They are getting steadily eroded by Temu and Aliexpress/Alibaba. Also in-person retail is surging for specific items - places like Best Buy have had a nice resurgence since the 2010s (stock is down compared to the pandemic, but that's a retail thing, not BBY problem).
bombcar•18m ago
Temu and the Alis are eating them alive on one side, and Walmart, Target, Best Buy (and even Home Depot) are destroying them on the other.
kylec•2h ago
I’m astounded, this has been a problem for 10+ years and I just assumed they didn’t care and would never change it. Better late than never, but why the sudden change?
notatoad•2h ago
yeah, this has been obviously a bad thing for so long, and they've been so stubborn, it's hard to believe anything has actually changed in the "economics" of it.

it smells like the sort of policy change that happens when an exec gets personally impacted by it.

mbreese•2h ago
It smells to me like the sort of policy change that happens when Amazon starts to worry about it affecting their bottom line and relationships with suppliers. It used to be enough to solve the problem with support/email. I do wonder what changed…
thepryz•1h ago
This. Amazon made a number of changes to the Fulfillment by Amazon (FBA) program related to lost and damaged inventory among other things. The changes risked increasing the costs and also required Amazon to be provided information that they really shouldn’t need, such as as the cost to source that inventory.

My assumption is that the decision to stop commingling is more to support these changes to the FBA program and allow them to extract more money via fees.

https://www.ecommercebytes.com/2024/12/22/amazon-drops-bombs...

SoftTalker•2h ago
I guess it's one thing to say you are going to do it and another thing to actually do it. Is anyone going to be verifying this? How would you? Mark your products and ask customers to check for the mark?
icelancer•1h ago
This has already been happening with a lot of vendors using the Transparency app.
JBlue42•1h ago
>but why the sudden change?

Tariffs maybe?

SpicyLemonZest•1h ago
I feel like this is one of the things where the most parsimonious explanation by far is to take their stated explanation at face value. It makes perfect sense that Amazon would insist on commingling when it's necessary to achieve fast shipping speeds, and end it if their logistics network is so good that it's no longer necessary. (Anecdotally, I just got an Amazon order to my doorstep in four hours yesterday - their logistics really are mindbogglingly fast now.)
Eisenstein•47m ago
They could have lost enough brand name vendors who decided not to deal with amazon because customers get counterfeit or expired products. Nike and Johnson and Johnson are mentioned in the article, but there are also smaller brands like ThermoWorks who were staunchly anti-Amazon because of co-mingling until very recently. I suspect it was due to a promise to end the process which brought brands back.

Due to a lack of a presence by name brands, Amazon has been devolving into a platform for selling drop-shipped no-name Chinese products. Whether this scared them because of long-term sustainability, tariffs, or just practical business sense is unknown.

ddavis•2h ago
Literally dealing with this right now. My wife got what appears to be a (very expensive) counterfeit item that is technically non-returnable (not laying down without a fight). Kind of cathartic to see this pop up.
codespin•2h ago
I received counterfeit goods multiple times due to this. I set up a subscribe and save order and they would let random retailers fill the order with fake products. Amazon collected the money and just did not care, they need to be held accountable for these things.
commandar•2h ago
> they would let random retailers fill the order with fake products

What made this all particularly insidious is that Amazon not only commingled inventory, but actively refused to track where inventory came from.

This meant you only needed one fraudulent seller to poison the entire inventory pool and there was no way know where the bad product came from because Amazon actively avoided being able to track it.

That's the aspect of it that always felt particularly malicious to me.

FredPret•2h ago
The bad part here is letting “poisoned” inventory in.

Adding vendor tracking adds a layer of ERP difficulty that isn’t practical for bulk, cheap items.

You either have to have serial numbers (unique per item, not just a product identifier barcode) or you have to physically segregate inventory by vendor, which is not practical.

If the vendor doesn’t serialize the item, then Amazon has to add it on receipt. Certainly not worth it for $10-20 item.

josefx•1h ago
> Certainly not worth it for $10-20 item.

Really? Adding a unique ID at the point of entry costs that much?

FredPret•1h ago
These things can have complications when you take into account all the edge cases. And paying humans/robots to do anything really adds up.

But at their scale, maybe they found a plan that works!

SteveNuts•46m ago
I thought Walmart has been doing this with their vendors for many years
jazzyjackson•17m ago
I read it as "For items in the ten to twenty dollar range, its not worth adding a vendor label" and I don't suppose its the cost of the sticker, but how much longer does it take the warehouse worker to take it from a shelf and put it in a box if they add a sticker to every item? +5% ? +10% ? +100% ? (It takes very little time to put an item in a box, I could see adding a sticker doubling this...)
diab0lic•1h ago
> or you have to physically segregate inventory by vendor, which is not practical.

The headline seems to indicate that the geniuses in logistics at Amazon have figured out how to make it practical!

londons_explore•32m ago
My understanding is every individual item is tracked in an Amazon warehouse - so Amazon knows that the 67th item in a box from supplier X was shipped to user Y.

They don't just track quantities of SKU's like most other retailers.

Retric•1h ago
They didn’t need to actually track things internally, add a sticker or even have someone stamp the vender code to the item listing the vendor when you’re adding the item to the bins and if the customer complains you can likely use that sticker to track who added the item after the fact. Critically you don’t need some 6 digit number for vender code, every new vender for a given item gets a number for that item, software can remember the relevant mapping.

If some vender is adding fraudulent items to the system based on some thresholds you set, charge the vendor to manually sort those specific products out.

Odds are they would make up the ~5 cents per item just dealing with less fraud. However, you don’t need to track every item rack the first few thousand items from a vender and you can scale back tracking as they prove themselves. At scale this could be almost arbitrarily cheap.

They are both correct.

defrost•1h ago
Vender has been a published word since at least 1596 according to the full Oxford English Dictionary.

You can find it in Francis Bacon's The Elements of the Common Lawes of England (printed 1630) - https://scholarship.law.wm.edu/oldelawebookes/28/

That said, vendor has become more and more the standard spelling in legal texts.

FredPret•1h ago
That’s a really clever and simple plan but doing anything like applying stickers, correctly, by hand or robot, can add cost ranging from $<surprising> to $<shocking>.

Maybe they have a variation of your idea where they inkjet a serial number onto a conveyor belt of incoming items or add a super-cheap chip of some kind.

Barbing•36m ago
>Odds are they would make up the ~5 cents per item just dealing with less fraud.

They’d be better stewards of the industry, but aren’t the odds that everything they’ve done for the past decade has improved their bottom line?

This is the company whose policies have effectively forced their drivers to use plastic bottles as toilets.

sillysaurusx•2h ago
It’s weird, every time I’ve talked to Amazon support they’ve always done well. Did they refuse to refund you or let you return it?
kwanbix•2h ago
Yeah, same for me. I don't like commingling either, but I could always solve it with Amazon's support.
Someone1234•2h ago
That's neither here nor there.

Amazon regularly commingling legitimate and counterfeit goods, means that customers are left with the job of trying to verify that the goods they ordered are legitimate. For every customer that complaints & refunds, there might be three or more who don't.

Some of these counterfeit products have legitimate safety concerns, for example lead paint usage, battery fire risks, PPE that misstates its effectiveness, or USB chargers with poor AC DC electrical isolation.

This is a huge trust problem, and "the customer needs to detect counterfeits and refund," isn't actually a solution to THAT problem.

londons_explore•28m ago
The solution is a regulator who buys random goods, thoroughly checks them, then fines Amazon for products found to be unsafe/illegal.

Amazon could then persue the manufacturer for sending bad goods.

a2128•1h ago
I bought an electronic item brand new, sold by Amazon, and they sent me a used one that already had its digital bundle redeemed by someone else and 5 out of 12 manufacturer warranty months used. I contacted Amazon support about this within a week and they told me replacement is not possible in my situation, I can return it but a full refund is not guaranteed
nenenejej•1h ago
What if the product causes harm? Fire for example or poisoning.
lyrrad•1h ago
I don't think ending commingling will stop that from happening, since Subscribe & Save is set to switch to a different seller with a lower price by default.

In the US, when Subscribe & Save is set up, it is set by default to receive orders from "Amazon.com and other top rated sellers". If you want to change it, you need to go into the Subscribe & Save page and change it to "Amazon.com only".

I've had an order where I initially placed a new subscription sold by Amazon.com, but a 3rd party seller would lower their price by a few cents, and Amazon would change the seller and I would receive grey market goods.

I haven't found a way to change the default for new subscriptions to always use the same seller that I set up the subscription with, so I need to manually change it for every single new subscription.

floating-io•1h ago
Thanks for this. I had no idea this was even a thing, and it explains some discrepancies I've seen with my one subscription.

They really don't make it obvious where to change it, either...

wdr1•29m ago
> Amazon collected the money and just did not care, they need to be held accountable for these things.

Whenever this happened with me, Amazon was pretty quick to offer a refund/replacement.

dboreham•2h ago
Rather suspicious this comes out a couple days after the articles about Walmart having issues with sellers shipping fake products.
GeekyBear•2h ago
The hassle of returning fraudulent or broken products has already driven me back to brick and mortar retail stores for items of any real value.
ViscountPenguin•2h ago
Just got hit by a counterfeit good 2 days ago. Thank god it's finally ending.
neilv•1h ago
As a consumer, this is great.

If Amazon can also ensure that every "Sold by Amazon" unit is legitimate (that they aren't sometimes sourcing badly), then it's 10x great.

(That I didn't feel comfortable enough trusting Amazon for some kinds of items is usually the only reason I've been buying direct-to-consumer from the brands' Web sites. I've had even Samsung and Crucial do DTC poorly in the last couple years.)

(Also, if I felt I could trust Amazon for genuine brand-name monthly OTC allergy products, that would mean no more hassling with the pharmacy chains. And maybe no more Walmart, though I don't recall a recent problem in their execution, and have been trusting them a little more than Amazon recently.)

buckle8017•1h ago
I literally do not believe they will do this.
woodruffw•1h ago
A serious question for the people in this thread who have bitten by this: why do you keep giving Amazon your business? Is it worth it despite these experiences?
thepryz•1h ago
I largely stopped buying from Amazon after receiving three counterfeit or defective products in one month. The only reason I buy from them now is due to a particularly low sale price or things I can’t easily source elsewhere. Otherwise, if ai can buy local or buy elsewhere I do.
akhleung•1h ago
I once was the victim of an empty box scam when I purchased an expensive item off Amazon a few years ago (luckily I got a refund), and since then I've used Amazon much less, and only for inexpensive things. Maybe enough people have reduced their spending such that Amazon has been forced to take notice.
GauntletWizard•1h ago
I more or less stopped completely. I spent nearly $10,000 on Amazon in 2016 (Multiple computers, clothes, games, foodstuffs - Just everything); It was down to $2000 by 2018 after I stopped trusting it for anything but big-ticket items that were unlikely to be counterfeit. It picked up again in the pandemic, but after a series of bad purchases in 2023 I've spent less than $1000 in the last year, and over half of that is a CPU that I really feared buying because of fraud/counterfeit concerns, and immediately inspected and installed to assuage those fears.
toomuchtodo•1h ago
I use Amazon to find a product but will then look for another channel to make the purchase, such as the product’s own site. I try to buy from Amazon as little as possible, and if I can only buy a product from Amazon, I’ll ask the product seller to give me a way to buy direct.

I would never buy a food or similar product that I would eat or use on my body from them. They simply don’t care about their supply chain integrity (aside from this bone they’re finally throwing to sellers and customers).

speff•23m ago
I tried making a serious effort of avoiding amazon lately. What I found was _generally_ prices are much higher everywhere else.

Charcoal pencils - 30% cheaper on Amazon compared to other sites. More than 2 times cheaper compared to local art stores and the local store only has one crappy brand in stock.

My watch - $40 plus shipping (2 weeks) directly from the manufacturer. Amazon has it at $28 and it'll get here tomorrow.

Pen nibs from Jetpen - $10 + $5.95 shipping. Once again >1week for delivery. $16 from amazon and it gets here tomorrow

I really feel like an idiot trying to boycott this company, but I'm still trying where I can.

bombcar•17m ago
Amazon has some things other sources don't, or has them at prices that make it worth the risk.

But for lots of "normal" stuff I use Walmart/Target to source it if possible.

freshtake•1h ago
A good move, even if many years late. It's a bilateral trustbuster when the same platform that allows commingling and knockoffs then begins tagging legit items as "frequently returned" in the feed.

Can we also get the ability to filter by seller entity country of origin?

Amazon also needs to offer far better tools for buyers to effectively find and attach to brands.

tchbnl•50m ago
This is an incredibly welcomed change. When I buy a product from a specific seller amongst a dozen, it's for a good reason. I expect THEIR inventory.
sangeeth96•46m ago
I wonder if this is a global change or just US only?
JCM9•19m ago
Was burned by counterfeit goods multiple times with my Amazon purchases. Their return policy is good, but still it was really annoying when I’d order something and you get counterfeit product.

They were cutting a lot of corners on quality control and it really started to show. Seems like this got to be a big enough issue they couldn’t just keep pretending like selling and shipping bogus junk wasn’t a real problem.
