I wonder how visible it will be when showing final charges for an order.

I'd definitely be more likely to "wait it out" when considering purchases in my cart if I can see what I expect will be a temporary levy.

exabrial•2h ago
We could immediately provide relief to fuel prices, while doing the climate a huge favor, by immediately suspending the USPS accepting marketing material through the mail.

My mailbox is permanently jammed with paper that useless paper that is both produced and hauled away to a landfill by diesel fuel.

No I do not want your credit card offer.

No I do not want to switch phone plans.

No I do not want an extended warranty.

jackling•2h ago
Not sure how it is in America, but in Canada you can post a note inside your mailbox stating that you don't want unaddressed mail.

What percentage of overall vehicular fuel use does junk mail (from inception to landfill) constitute, might you suppose?
Teever•2h ago
It's not just the vehicular fuel that goes into this process, it's the growing the trees, harvesting them, making them into paper, then combining that paper with ink that likely has a similarly complex supply chain on a printing press that consumes a lot of power.

Getting flyers that are subsidized by the post office for stuff like lawnmowers and patio furniture even though I live in an apartment is peak absurdity.

lenerdenator•1h ago
I live in what was a family member's house before her passing in 2014.

I still receive her mail.

Here's the kicker: the mail is addressed to a name she hadn't legally had since the late 1970s. She divorced and remarried - which meant taking her new husband's last name - then lived another 30-ish years, died, I moved in, and it's been ten years of me there.

It's an insanely wasteful practice.

singleshot_•11m ago
Write “rejected” on all the mail you don’t want and leave it unopened in your box. Cuts it down nearly to zero after a few months.
digitalsushi•2h ago
If the majority of mail stops are junk mail only, I would love to see some napkin math of the effect of all those diesel/gasoline accelerations per mailbox, dropped across the daily fleet of drop offs.
slillibri•1h ago
Stopping marketing mail wouldn’t change the number of accelerations per mailbox. USPS would still need to check each stop for outgoing mail. The only difference would be in weight carried.
jghn•1h ago
Depends. Where I live outgoing mail goes into the closest blue USPS bin. And given that most days all mail I receive is slop, removing the slop would remove the need to come to my house.

Of course, where I live the USPS person stops in a general area and does all the outgoing deliveries on foot, but it's conceivable that some days an entire block may receive no incoming mail. Also, we need to take into account things like fuel costs for planes & such throughout the entire supply chain.

mikestew•1h ago
USPS would still need to check each stop for outgoing mail.

No they don’t, that’s what the red flag on the mailbox is for. Everywhere I’ve lived, if you don’t put the flag up and there’s no incoming mail for you, they don’t stop.

tshaddox•1h ago
Percentage of mass is probably the wrong metric to look at, because it assumes that the USPS could simply eliminate the X% of mass used by junk mail and save roughly X% on fuel/delivery costs.

But of course the issue is that the junk mail is subsidizing the actual mail. There's likely no way the USPS could be financially solvent, at least with the current level of service, if junk mail were eliminated. Personally I'd be fine with that. One or two mail deliveries per week would be more than enough!

ssl-3•1h ago
I think the real issue in this context is the 3.5% surcharge that Amazon may add, and whether or not elimination of USPS junk mail could ever make a dent in that 3.5% figure.

(My gut says that it would not; that the fuel use of junk mail constitutes a very small drop in a very large bucket. But I'd love to be wrong about this.)

calvinmorrison•2h ago
In FY2022, fuel consumption was 221 million gallons of gasoline equivalent, with gasoline or diesel making up 99%. USPS fleet greenhouse gas emissions (GHGs) made up 70% of overall GHGs for federal fleet vehicles in FY2022.

50-60% of all mail is marketing slop

exabrial•1h ago
Honestly I'd be surprised if it's that low. My guess is by weight its closer to 85%-95%.

Your numbers show exactly what I was guessing to be true though. Incredible this has never been enforced.

mrguyorama•1h ago
Mail delivery vehicles have to travel roughly the same paths as long as there is most anything to deliver.

That's what makes it a public service.

Junk mail just makes stamps cheaper. That route had to be driven anyway. You have generally what amounts to a right to put a stamped letter in your box at the end of the driveway, put up the flag, and get serviced. The route has to be driven regardless.

We could eliminate all marketing mail, make a large push to make all billing digital, and USPS would still have to drive most routes most days.

A fix would have to reduce service significantly, or introduce a new "Register for pickup" process to signal your need of service.

We could have also made those brand new mail vehicles hybrid or something.

mikestew•1h ago
$8, and that all stops for ten years: https://www.dmachoice.org/static/consumer_choice_tools.php

I’ve done it (several times, ‘cuz ten years), you’ll notice an almost immediate reduction in junk mail.

youarentrightjr•1h ago
Sounds like a racketeering operation (not saying it doesn't work).
mikestew•1h ago
It indeed has a fishy smell to it. But as I thought through it, if it were free then some bozo would spam an entire address database and then we can't have nice things anymore. The ten year expiration is sketchy, but I guess someone is hoping you'll let it expire (I've never received a "renewal notice", as it were.) And, yeah, "nice mailbox, shame if it got filled with shit you didn't ask for."

OTOH, for less than a dollar a year, I can go find other clouds to shake my fist at.

usefulcat•1h ago
Reducing the frequency of mail delivery would have a much larger impact, since most of fuel is probably consumed by last mile delivery.

Delivering less mail each day doesn't really make much difference if the mail carrier still has to come to my neighborhood 6 times a week.

browningstreet•42m ago
Fewer mail carriers could hit twice as many places in a given time-frame and reduce overall gas usage.
lokar•1h ago
A lot of the USPS budget is from delivering bulk mail. They already fail to break even (albeit with absurd retirement funding rules imposed on them). Without the fees from bulk mail they would need to raise prices, and it's not entirely clear they could given they face strong competition.
SoftTalker•1h ago
I don't really understand why we need a US Postal Service in 2026. Yes, the Constitution grants congress the power to establish "post offices and post roads" but it doesn't mandate it AFAIK.

Other countries (Denmark is an example) have completely privatized physical mail delivery. All official mail is electronic. There's some nostalgia for the postman on his red bicycle (or in the USA, walking the neighborhood or driving their funny looking trucks) but are they really necessary?

Edit to add: since running post offices is explicitly a Federal power, a conversion of US Mail to being electronically based would be completely within scope. There would be no arguing over "states rights" that tends to become a logjam for any other national infrastructure or policy changes.

lokar•1h ago
I think it's mostly not needed, but there are a lot of edge cases or narrow situations where it's important. They could be fixed, but no one is doing that.

IMO, a better option is to switch to 3 days/week delivery, and where addresses are very spread out, require centralized boxes.

michaelt•52m ago
Traditionally, the state has certain duties it needs to perform for every member of the population.

Passports, driving licenses, polling cards, draft registration, pensions, company registrations, patents, copyrights, court summons, speeding fines, inheritance, tax paperwork, census, etc etc.

It’s much simpler to perform these duties if you have a means of communication that can reliably reach every citizen.

SoftTalker•30m ago
I'm not sure I'd put "reliable" in any description of the USPS. I get my neighbors mail in my box often. I can only assume some of my mail gets delivered to them as well.
stryan•46m ago
Practically speaking, USPS does a lot of last mile package delivery that no one else wants to do, including Amazon. If USPS wasn't delivering to those locations no one would be. And we're not talking middle-of-no-where-Wyoming locations, plenty of places east of the Mississippi have only USPS too.

There's all sorts of philosophical arguments as well: government services shouldn't need to turn a profit, all citizens need to be able to interact with the State and the post office provides a way to do that, mail-in voting, Post Offices can offer stuff like general delivery for those without permanent addresses, etc.

hadlock•35m ago
You need a non-electronic way to bill land owners for property taxes. That's it. Physical snail-mail is the de-facto way for the government to legally serve property taxes and other bills to private citizens. Yes we live in 2026 and everyone has email, but there's no legal requirement to give the government your email address, or even have one. You are however, legally required to provide a mailing address for your property tax bill to be sent to.

Sure, by that standard we could probably reduce to weekly or even monthly mail service. It's been suggested since at least 2008 we drop Tuesday mail service as almost nobody sends mail on Saturdays and there's no mail service on Sundays.

Last year, Amazon backed down from sharing tariff pricing. I assume the same will happen here.
djoldman•1h ago
I immediately thought of that move.

This time I think the surcharge will stay until the war is concluded.

cogman10•1h ago
Yeah, but amazon isn't going to list it as a line item. Which they should.
t1234s•1h ago
Does that 3.5% get passed to the seller if they are not using Amazon to ship the product?
gnabgib•1h ago
Title could really use "for third-party sellers who use fulfillment services" (this is not a 3.5% surcharge on AWS, Prime, or Amazon orders)
zoover2020•54m ago
It was pretty clear to me. AWS is Web Services after all
jrockway•1h ago
Sometimes I wonder if we just do these wars so that companies can raise prices and when the war ends, not lower them. Do we ever see "oil prices are down 3.5%, we are lowering our prices by 3.5%"? Never. "But the free market will force someone to do this to gain marketshare." But Amazon is the only Amazon, so I doubt that will happen.
crazygringo•1h ago
> Do we ever see "oil prices are down 3.5%, we are lowering our prices by 3.5%"? Never.

Companies lower prices all the time. It's the competitive market at work. They just don't tend to say why, because nobody cares about the reason, so it's not necessary.

E.g. snack prices are coming down, to pick one recent example: https://www.npr.org/2026/02/03/nx-s1-5697941/pepsi-prices-ch...

But it's human bias to notice when things get worse, but not when things get better.

jeromegv•20m ago
Absolutely in a competitive market.

There’s an argument to be made that Amazon has so much of the online buying market that’s it’s not competitive and can likely get away with increasing price. And I tend to agree with that

binarysolo•1h ago
Amazon third party seller (low 8s) here: last time this happened was during COVID and it ended up being a permanent FBA shipping price increase.

Practically speaking shipping accounts for 10-20% of the sale price, so realistically it's the seller who will absorb it and maybe pass on costs to the buyers, but we're talking about 3.5% of 10-20%, which is really a 1% price increase, so a noticeable but not make-or-break issue in the death-by-1000-cuts.

The Andy-led Amazon is less forgiving than the Jeff "your margin is my opportunity"-led Amazon on profitability so price shocks have passed through to sellers much more immediately than prior years where Amazon would just move slowly and stably.

The bigger Amazon news recently is on DD+7 and how Amazon basically increased their float and delayed payments on all sellers, and that's been kinda a pain to navigate.

zobzu•1h ago
i fully expect it yo be permanent. they know its likely to come back down.

Do you buy off Temu and re-sell on amazon?
binarysolo•15m ago
I dunno why that's a whole meme, but nobody of any scale is doing that. We produce products through factories like most established sellers.
jazz9k•19m ago
I made a living selling on Amazon about 15 years ago. It all came crashing down when they held all of my money (around $50,000) and had to 'investigate'.

Nothing ever came of it and they released my money, but banned my seller account for 10 years.

It was actually a good thing. I started my own site and made a good living for a decade. Covid shutdown the business.

Building a business on Amazon is a mistake.
