Amazon's 2026 fee announcement said referral and FBA fee rates wouldn't rise and no new fee types would be introduced, yet my settlement has carried a separate fuel surcharge line since April 17 that's calculated as a percentage (the published rate is 3.5%) on top of the fulfillment fee. I get the argument that a surcharge isn't technically a "fee", but it hits the same payout either way. Do you model it as a fee increase when you do your pricing math, or as something temporary that will go away? Curious how others are treating it in their margins right now.

I set a $40 daily budget on a Sponsored Products campaign and let it run. The dashboard shows $61.47 spent on the 14th, then straight back under $40 the next morning, and the rest of the week lands right on target. I don't open the ads tab daily, so I only caught it while reconciling September — which makes me wonder how many of these one-day spikes I've already paid for without noticing. Does your invoice ever match the cap, or do you just budget around the blown days? Anyone else seeing this?

I line my settlement's storage charge up against my inventory ledger every month, and October opened weird: the fee is billing on 420 units, but only 300 were actually in the FC on October 1st — the other 120 checked in on October 3rd. September's storage line was $470 and October's is already at $612 on basically the same sell-through. I know the Q4 rate is higher, but that alone doesn't explain a $142 jump for me. Does Amazon prorate storage daily for units that arrive mid-month, or do I need to time check-ins to the calendar month?

I've held Featured Offer on this listing for about 14 months and I'm at $18.99, but since Monday a seller at $19.85 with 3-day handling took the slot and my sessions are down roughly 30 percent. Nothing changed on my end: same stock, same feedback score, same ship speed. Is anyone else seeing Featured Offer flip to a higher-priced seller with worse metrics this week, or did I miss an eligibility change?

My patio set crossed the category return-rate threshold back in July, and now every returned unit gets hit with a returns processing fee on top of the fulfillment fee I already ate. Last month it was 41 returns on that single ASIN, and the fee shows up as its own line in every settlement now. Returns were already painful, but at this rate I'm re-pricing whether the variant is worth keeping live. Anyone else in a high-return category watching this quietly eat the margin?

Somewhere along the way I stopped optimizing for margin and started optimizing for never running out, and I do not think I ever priced that decision.

My setup now: about five weeks of cover sitting in FBA on the main SKUs, plus another three weeks parked at a 3PL as an inbound buffer. On paper that is the responsible thing to do. It keeps me clear of the low inventory threshold, it absorbs a slow boat, and I have not had a stockout quarter in a long time. What it also does is tie up roughly 45 percent more capital than holding a single cycle would, and that capital is not free.

The part that bothers me is that I never put it in the unit economics. My product still shows a healthy gross margin per unit, so I kept telling myself the buffer was just working capital that comes back. But the whole batch turns slower now. The same money, cycling less often, gives me something closer to 19 percent on the batch instead of the 28 that the per unit margin implies I am earning. Nothing on the listing changed. The clock did.

So the honest question: is everyone else quietly carrying this and calling it the cost of doing business, or is someone out there modelling buffer stock as an explicit line item in their unit economics? If so, how do you decide the right size — insurance against stockouts versus the drag on return? And has anyone actually compared doing this against just accepting a short stockout occasionally? Anyone else seeing this?

I have been assuming the low inventory fee was a monthly thing — start the month thin, end the month thin, you get hit; average it out and you are fine. That assumption just cost me money.

Here is the month that broke it. I started with about 50 days of cover on my main SKU, sold faster than forecast, and finished the month around 20 days. Average for the month lands near 35, comfortably above the line I was watching for. And I still got charged for low inventory, which made no sense to me until I read how it is actually assessed.

The fee is not measured on your monthly average. Amazon looks at days of supply on a rolling basis, day by day, against recent sales velocity. If you dip under the threshold on any single day, that day counts as a low inventory day. At month end they total the days you were under and charge you for them. So a month that looks fine on a spreadsheet can still be a month you paid, because the average hides the dip and the dip is what gets charged.

Which means my whole restock trigger was built on the wrong number. I was watching the monthly picture and the thing that bills me is a daily one.

Anyone else got caught by this after the FNSKU level change? How are you tracking daily cover — are you pulling the inventory report every day, or have you found a way to set an alert that fires before you slip under instead of after? And does anyone know whether the exemption for slower moving items is evaluated on the same daily basis or monthly? Anyone else seeing this?

Something I think I had wrong for about two years, and I want to check whether I am the only one who read the fee base this way.

I always mentally modeled the referral fee as 15 percent of the item price. So on a 24.99 dollar listing I expected roughly 3.75 in commission and I priced around that for a long time. When I finally sat down with the transaction detail on an order where the buyer paid for expedited shipping, the commission was closer to 4.80. Not a rounding difference, a real one.

What I had missed is that the fee base is not just the item price. It is the total the buyer pays, which includes the shipping charge and the gift wrap if they add it. So a listing at 24.99 plus 6.99 shipping is being commissioned on 31.98, not on 24.99. On a low priced item that gap is small in dollars but it is a straight hit to the percentage you thought your margin was.

I only caught it because the buyer-paid shipping was a new thing for me on that SKU, and the fee moved in the same direction and by roughly the same proportion. If your listings are all free shipping you would never see it at all.

Anyone else already modeling it this way, or did this catch you too? Do you fold the buyer-paid shipping into your price and go free shipping to keep the base predictable, or leave it and just budget the extra commission? And for anyone in a category with a higher rate than 15 percent, does the shipping piece get commissioned at that higher rate as well? Anyone else seeing this?

I spent the first three months of a new product feeling like I had finally got the unit economics right, and then month four quietly took it back, and nothing on my side had changed.

Here is what I missed. New launches get enrolled in the FBA New Selection program automatically, and it is more generous than I realized: a rebate on FBA fulfillment fees, free monthly storage for a while, free removal or liquidation, and free return processing. Individually none of those sounds like much. Together, on a 600 unit batch, they were enough to make a product that nets a thin margin look like it nets a comfortable one.

My first three months were showing something around 22 percent net. Month four came in near 14 with the same price, the same ad spend, the same everything except the rebates winding down. So for three months I was reading a number that was real but temporary, and I made inventory and pricing decisions on it.

The uncomfortable part is not the money, it is that the discount did not announce itself either. There was no line item that said this is ending. I only caught it because I reconcile the settlement report line by line and one month the fulfillment fees simply stopped being offset.

Anyone else map out exactly what the incentive period is worth per unit before they commit to a launch price? Are you pricing the product as if the rebates do not exist, or using them to fund the first ad push and then re-solving? And has anyone seen the program terms shift on them mid-launch? Anyone else seeing this?

I made the boring decision in August: my unit margin was fine on paper but the ad line was eating it, so I took my monthly ad spend from about 4,000 dollars down to 2,400. Same products, same prices, I just killed the keywords that had never converted and dropped the bids on everything else.

It worked exactly as intended on the cost side. My TACoS went from about 9.4 percent to 7.1 percent and my per unit cost of advertising dropped by roughly a third. For three weeks it looked like free money.

Then the organic side moved. My organic sessions are down about 22 percent over five weeks and two of my main keywords dropped off page one. Apparently a chunk of what I was buying was not just sales, it was the rank that made the sales. So I am now sitting at roughly the same net margin as before, except I am selling fewer units doing it, which is a worse business even though the dashboard looks healthier.

The obvious answer is to turn it back up, but then I am back to buying rank at a loss and calling it growth. I have not found the middle point yet.

Anyone else tried the cut and had the organic fade show up with a delay like this? Did you find a spend level that holds rank without the bleed, or did you just accept lower volume? Anyone else seeing this?

I moved a SKU from $17.49 to $17.99 last month expecting about $0.50 more per unit, and my net per unit came back down by roughly $0.40. It took me a week to believe the settlement report.

When I mapped it out, the reason is that fees do not move in a straight line. The roughly 15 percent referral sits on top of everything, but the fulfillment steps and the size tier boundaries mean there are narrow bands where a small price increase tips the unit into a higher cost, and the price move is too small to cover it. I found two bands in my own catalog where the lower price genuinely nets more than the higher one a dollar above it.

I know edges like this have always existed, but with the fuel surcharge and the 2026 fulfillment changes stacked in, the dead zones feel wider than before, and I no longer trust the margin my calculator shows me at a price I have not actually tested.

Has anyone else mapped their own dead zones? How wide are they for you, and do you just park the SKU at the lower number and stop touching it?

My supplier is quoting me 8 to 10 weeks door to door right now, and every guide I read says the low inventory safe zone sits somewhere around 28 to 60 days of supply. My lead time is 56 to 70 days. The window I am supposed to live in is shorter than the time it takes to replace the stock, which means the target and the supply chain cannot both be satisfied at once.

Concrete version: I run about 40 days of supply on my main SKU, which sounds healthy until a 9 day customs delay puts me at 31 days by the time Amazon takes its snapshot, and one slow restock week drops me under the line. If I raise inventory to stay safe, I pay peak storage on the extra cubic feet. If I keep it lean to save storage, I am gambling on the port. There is no setting where both numbers are happy.

Ordering earlier does not really solve it either. The cash just sits in inventory for two months doing nothing, and my reorder point turns into a guess about shipping lanes rather than a decision about demand.

Anyone else stuck in the same arithmetic? Do you run permanently overstocked on purpose, park the overflow with a 3PL, or just eat the fee a couple of months a year? Anyone else seeing this?

I was rebuilding my Q4 margin model this weekend and noticed the two fee windows don't actually cover the same dates, which changes my plan more than the fee amounts do.

Peak storage for standard size goes from $0.78 to $2.40 per cubic foot starting October 1 and runs through December 31, resetting on January 1. Peak fulfillment, on the other hand, doesn't start until October 15 and runs all the way to January 14.

Two things fall out of that, and I think most of the checklists I have read get both wrong.

First, if October 1 is when the storage rate jumps, then that is my real deadline for clearing aged and slow stock, not October 15. Anything sitting in a fulfillment center on the October snapshot pays peak storage for the whole month regardless of when in October it sells. Removal and liquidation take weeks to process, so the actual decision lands in mid September, which is basically now.

Second, a unit that sells in early January pays a peak fulfillment fee on already-reset standard storage. That is the combination that would have confused me when reconciling January settlements.

The other thing I keep going back and forth on: I have a couple of SKUs that are genuinely seasonal, where unsold units have no real Q1 demand to fall into, and I think the answer there is obviously to buy tight and clear before October 1. But for the evergreen ones I am not sure whether the storage cost of sitting through October is actually big enough to justify buying conservatively into a quarter where my demand forecast error skews up.

Has anyone actually modeled the October 1 drawdown separately from the October 15 fee start? Am I overthinking the storage side, or is that two week gap where people are quietly losing money?

I have a shipment that was planned against the Florida node and I only found out PBI3 in Port St. Lucie is closing permanently on September 17 when I went looking for why my inbound splits had changed.

As I understand it, after the 17th inventory that used to route through PBI3 gets reassigned to nodes in Georgia and Alabama, which does three things to me at once. My delivery promise to South Florida ZIPs gets worse, my default inbound split recommendations get recalculated against a new node map, and the placement fee math on the same inventory can come out different than what my current shipment plan assumes.

What I cannot figure out is the in-transit case. Amazon can reroute shipments when a facility closes, and the guidance I have read says a reroute initiated by Amazon should not generate an inbound defect fee on top of whatever placement fee already applied — but the same guidance says the automated system does not always distinguish an Amazon-initiated reroute from a seller error. At $0.60 a unit for the consolidated inbound defect fee, that ambiguity is not cheap on a few thousand units.

So two questions for anyone who has been through a facility closure before.

One, if Amazon reroutes my shipment off PBI3, does the placement fee get recalculated at the new receiving location, or does the originally assessed fee stand? I cannot tell from the fee documentation which one applies.

Two, what is the actual evidence I need to keep to win a defect fee dispute if one shows up. I have the original shipment plan saved and the receiving location change, but I do not know whether that is enough or whether I need something from Seller Support in writing before the 17th.

Anyone else sitting on inventory aimed at the Southeast right now? Did you proactively contact support, or did you just wait and see what the system did?

Running PPC for about 8 months now in home & kitchen. Was sitting at a comfortable 22% ACOS until April, now it's creeping up to 35%+ and I haven't changed my bids or targeting.
I think the fuel surcharge is eating into my margins so my break-even ACOS shifted, but I'm not sure if I should just accept thinner margins or actually cut ad spend. Anyone else in the same boat? How did you adjust?
