> [@papy](#): > > glitch that they didn’t even find for a month? Not a glitch. This was a failure to execute. Amazon was getting ready to allow sellers to link their own USPS accounts to Amazon about the same time. Probably just held back to accommodate their engineers and/or bots. That’s not a glitch but a business decission. ---

> [@SellerFeller](#): > > It seems to me that if you have entered the weight and dimensions correctly, that Buy Shipping should accurately display the actual label cost (meaning no future surcharges). Am I missing something? A common UPS surcharge is address correction. And it is a hefty surcharge $25.25 per package plus fuel surcharge. I have no experience with how Amazon currently reports this charge. ---

Just a follow up … Originally from our email from Amazon, all of our adjustment were to be done between Sept 7 and Sept 10. The final adjustments hit on Sept 12. All of the adjustments total matched the email’s stated total … so no surprises. All of the adjustment dates were between Jan 18 to Feb 18 as we expected and had noted on our excel tracking sheet. Sales were at a trickle during the adjustments, but, to be fair, this time of the year (September) is normally a slow period for us … so it is a little hard for us to say if Amazon throttled sales while doing the adjustments. Now …quietly awaiting the start of Glitchmas … ---

My last adjustment showed up on 9/11, for a 1/20 label that should have been $5.52 instead of what amazon charged us as $5.15. I made the following post in another thread on Jan 20th: > [@2026 First Postal Increase of the Year](https://sellersasksellers.com/t/2026-first-postal-increase-of-the-year/6864/8): > > I’m purchasing a GA label for a 3 oz, zone 8 package on Amazon Buy shipping this morning. Looks like Amazon hasn’t updated the prices yet, it’s still same as before $5.15. > > I hope this is not going to be a problem. Is USPS going to come back to charge me extra later, or would Amazon pay it out of their pocket since it’s their fault. Well after almost 8 months, both questions were answered. USPS did came asking for more money (why waited so long?), and Amazon didn’t take the responsibility of their fault. 😒 ---

AMZ does not use a direct pass-through API for USPS rates nor do they use a direct pass-through API with mark-up. AMZ takes USPS rates which are lower than the up to 31% discount rate they pass on to us. AMZ negotiates rates to 40 to 50% below retail then adjust to around 31% off retail for us. But AMZ uses their own convoluted algorithm to reach that rate and not a straight mark-up percentage like other 3rd party postage providers. > > Amazon generates adjustments when: > > - their internal dimension database flags a mismatch > - their internal weight database flags a mismatch > - their internal service‑level classifier thinks you used the wrong service > - their internal zone calculator thinks the zone was wrong > - their internal USPS‑mapping system misreads a scan > - their internal audit system reprocesses old shipments > - their internal “delivery‑speed model” recalculates risk > - their internal “carrier reliability model” recalculates risk > > These adjustments are not USPS APV. > > They are Amazon‑generated, and they often have nothing to do with the actual package. > > They are created because Amazon’s audit system is: > > - aggressive > - automated > - error‑prone > - poorly calibrated > - overly sensitive > - sometimes months behind > - sometimes reprocessing old data ---

> [@Dogtamer](#): > > AMZ negotiates rates to 40 to 50% below retail then adjust to around 31% off retail for us. Not sure we believe this part. So Amazon makes 9% to 19% off of USPS? Nope. It was clear to us that Amazon didn’t execute the Jan 2026 price increase until 30 days later and, when they did, the prices became the same as other providers like PirateShip. Then 8 months later, charged the sellers for the difference of the miss charged labels and tried to pass it off as a USPS thing. ---

> [@Lost\_My\_Marbles](#): > > Not sure we believe this part. So Amazon makes 9% to 19% off of USPS? My belief is they must make somewhere in this range to cover A-Z protected claims. I don’t believe they do this out of kindness to 3p sellers. ---

As a slightly different take on our own “adjustments”, we don’t use Amazon shipping, instead use Veeqo. I haven’t seen any adjustments on Veeqo of our outbound shipping, somehow they get it right the first time (despite being part of Amazon). What I have seen is the for EVERY return (which come by UPS of course), there is eventually an adjustment. Half of those are $.01. The other half range from $.11 to $.88; over the course of 2026, we’re out $1.75 total. That’s it. P.S. As far as what has been discussed above, this is likely intended malfeasance (or at best gross incompetence) and not honest business. Part of the Amazon Marketplace culture. Just my two cents. ---

gotta agree with @svbooks every shipping adjustment we get is for returns. Every single return. sometimes as little as $0.04 the most luckily was $8.48 because they shipped the item in a 10x12x4 box and it was originally shipped in a 6 x 10 padded envelope. ---
