Prime Day FBA Returns: The August Wave Sellers Don't See
4 days. Record sales. If Prime Days 2026 went well for you, congratulations. You earned it.
In 3 to 6 weeks, something else is going to land at your warehouse. It will not arrive with fanfare. It will not show up on your revenue dashboard. But it will show up on your bottom line, and it will do it at the worst possible time: right in the middle of AUGUST.
This article is about the other side of Prime Days. The side that does not make it into the celebration posts: PRIME RETURNS.
๐ The Other Side of the Coin
Every major sales event has a mirror image:
-
For Black Friday, the mirror is January. I covered the mechanics of that wave in detail in FBA Profits at Risk: The Amazon FBA Holiday Return Trap.
-
For Prime Days, the mirror is August. Fewer sellers plan for it, because fewer sellers think of Prime Days as a returns event. They think of it as a sales event. It is both.
The mechanism is the same: a customer buys under time pressure, regrets it, returns it. Amazon processes the return, creates a removal order, ships it. By the time it arrives at your warehouse, Prime Days is a distant memory. And the reimbursement clock is already running.
๐ก๏ธ Heat + FOMO: A Combination Nobody Plans For
This year, something amplified the usual Prime Days return dynamic. Two forces were active at the same time.
The first force is FOMO: the fear of missing out. Prime Days deals are time-limited by design. Customers know they have a narrow window to decide.
They buy faster. They read product descriptions less carefully. They skip the pause that normally separates an impulse from a purchase.
The result is a cohort of buyers who are statistically more likely to regret their decision once the urgency lifts.
The second force is the weather, Very Hot Temperatures.
June 2026 brought record temperatures on both sides of the Atlantic. Parts of southern Europe pushed above 39ยฐC. As I am writing this, my A/C is going non-stop.
This is not a regional footnote: it is a global customer base stuck at home, browsing more than usual, and running low on patience, because they sweat a lot.
That combination matters for returns. A product that would be "good enough" in October becomes a return in June. Not because the product changed, but because the customer's tolerance did. A product they might normally keep gets sent back when they are already irritable.
FOMO + HEAT = MORE RETURNS
But it is something you will feel in August.
๐ฌ What a Seller Told Me This June
A seller I know, Gianni, runs an FBM operation selling garden tools and outdoor equipment alongside his FBA catalog. His team handles customer support directly, which means they see every buyer interaction in real time.
In June, Gianni started tracking something unusual. More than 50% of the customer support tickets his team received that month were not actual product problems. Customers writing in confused about things covered in the instruction manual. Basic setup questions. Threats to return a product over an issue that resolved in a single reply.
"They are not angry at us. They are just hot and not in the mood to read." - Gianni L.
This is an FBM operation, so Gianni sees the conversation directly. FBA sellers do not. But the same customers are buying from both channels.
Have you seen something similar this June?
I would be curious to hear from sellers who track customer contacts.
๐ The Data: What We Measured on Prime Day 2025 Orders
Field observations are useful. Data is better.
We pulled the return rate data for 3 Eagle Eye customers and compared their Prime Day 2025 orders against their standard weekly baseline from the same period.
The result: an average 27% increase in the return rate for orders placed during Prime Day 2025, compared to the preceding weeks.
The only question is whether you will be ready for it when it arrives.
๐ When the Wave Actually Arrives
This is the part that catches sellers off guard.
The returns from Prime Days do not arrive this week. They do not arrive next week.
- Amazon's return window gives customers up to 30 days from purchase.
- Then Amazon processes the return, which takes additional time.
- Then a removal order is created.
- Finally, the removal order is sent in different shipments.
Total Time: 3 to 6 weeks
Amazon Prime Days 2026 ran June 23 to 26. Add 3-6 weeks, and you are looking at mid-July through early August at the earliest.
That is exactly when this wave is going to arrive.
For European sellers, particularly in Italy, August is the month when warehouses run on skeleton crews, or close entirely. It is the month when the team is at the seaside, the phones are on do-not-disturb, and the last thing anyone wants to deal with is a stack of removal boxes.
Unfortunately, FBA reimbursement windows do NOT go on holiday.
Amazon gives you a fixed period to dispute return frauds, damaged goods, missing units, and incorrect condition labels. If nobody is watching in August, those windows close. The money is gone.
โ Two Things to Do Before You Head to the Seaside
Prime Days just ended. The wave has not arrived yet. Here is what to do in the next 3 weeks.
"The time to repair the roof is when the sun is shining." - John F. Kennedy
First: decide what you are doing with your removal orders in August.
If your warehouse is staffed in August, no change needed. If it is not, consider pausing automatic Removal Order creation temporarily.
A Removal Shipment that arrives with nobody home is not just a logistics inconvenience. It is a reimbursement claim that cannot be filed because the physical inspection never happened.
I wrote about the full relationship between returns, removals, and reimbursements in Why FBA Returns, Removals, and Reimbursements Are One. If you are new to the R3 cycle, start there.
Second: start your FBA reimbursement review before August, not after.
Amazon's fulfillment centers were running at peak capacity in the weeks leading up to Prime Days, processing a surge of inbound shipments from sellers preparing their stock.
Busy Fulfillment Centers produce more discrepancies:
- units lost at receive
- units damaged or lost
- units in transit between FCs.
If you sent inbound shipments in May or June, the chances that something went wrong is higher. Those claims have the same deadlines as return claims. Filing them in September produces nothing.
If you want to understand the full landscape of what you can claim, Every FBA Reimbursement You Can Claim in 2026 covers each category with the relevant windows and evidence requirements.
Your reimbursement window does not go on holiday. If you are wondering what it would look like to have someone watching it for you, Eagle Eye is where to start.
