Amazon's 2026 pricing rules: what sellers need to know

Run your price below its usual level for too long this year and Amazon may quietly decide your product is worth less. Your strike-through discount shrinks or disappears, and it takes months to win it back. That's the blunt version of what changed in 2026, and it's caught out sellers who thought they were just being generous.

Here's the thing most people miss. Amazon shows a "typical price" next to many discounts — the reference that makes your deal look like a deal. It's normally worked out as the median price shoppers paid, excluding promotions, over the last 90 days. From 18 May 2026, that number got teeth. Let's walk through how it works now, what does and doesn't count, and how to run promotions without accidentally lowering your own reference price.

The 50% rule, in plain English

Amazon looks back over a rolling 90 days and checks how many of those days your price sat below the usual (non-promotional) median.

If that's more than half of the days — so more than about 45 out of 90 — Amazon stops treating your full price as "typical". It recalculates the typical price using all your sales, discounted ones included. The reference drops to match what shoppers have actually been paying.

Once that happens, your strike-through saving shrinks or vanishes, because Amazon no longer believes the higher price is normal. Any discount you run afterwards is measured against the new, lower reference, so it looks smaller to shoppers. And getting it back is slow. Because the window is 90 days, sellers who've been through it report needing roughly three months of sales at the higher price before the reference recovers.

Think of it less as a penalty and more as Amazon calling your bluff. If your product sits at "20% off" for most of the quarter, then 20% off is the price.

What doesn't count (this is the important bit)

This is where a lot of the early advice on the rule went wrong. According to Amazon's guidance, as reported by the trade press, several things are excluded from that recalculation:

• Coupons
• Buy X Get Y offers
• Subscribe & Save discounts
• Peak-event pricing — Prime Day and Amazon's other big deal events. Amazon has said peak-event sales are always left out of the typical price calculation.

What does count is your everyday price. A sale price you leave running for weeks, or a quiet price cut that isn't presented as a promotion, is treated as your normal price, and that's exactly what pulls the median down.

In other words, the rule mostly bites sellers who run long, rolling "sale prices", not the ones who use coupons or join Prime Day.

Same product, two pricing calendars. One stays under the line; one crosses it and lowers its own reference price.

The other 2026 change: list prices need proof

There's a separate rule that came in on 23 April 2026. If you enter a List Price (the "RRP" a strike-through compares against), Amazon now wants evidence for it. Broadly, the product needs to have actually sold at that price on Amazon, or another retailer needs to have offered it at that price recently. If Amazon can't back it up, it won't show it.

So an aspirational "RRP £49.99" on a product that has only ever sold at £29.99 is now likely to disappear from your listing.

Why Amazon's doing this (and why it's not entirely mad)

Amazon hates fake urgency. A strike-through price that's been "on sale" for 300 days a year isn't a sale, and it erodes trust in the whole marketplace. Both rules force the reference price to mean something.

We actually think the intent is fair. (We're not always this generous about Amazon's rule changes.) A genuine £29.99 product with an occasional real discount is exactly what Amazon wants shoppers to see. The collateral damage falls on sellers who leaned on near-permanent sale prices as a conversion tactic.

So how do you actually protect your margin?

You don't stop running promotions. Discounts still drive rank, reviews and velocity. You just choose the kind of discount more carefully.

Count your below-price days. You've got roughly 45 days in any 90 where your everyday price can sit below its usual level before the reference is recalculated. Spend them deliberately.

Kill your zombie sale prices. Look for sale prices and price cuts that have been quietly running for months. We find these on a lot of accounts we take over — a reduced price set during a launch and never put back. Those are the ones that count against you.

Use the promotions that are excluded. If you want a regular discount, a coupon, a Subscribe & Save offer or a Prime Day deal does the job without dragging your typical price down. That's a real shift in how to plan promotions in 2026.

Make sure your list price can be backed up. Check any List Price against what the product has actually sold for. If you can't evidence it, it won't show anyway.

Grow with levers that don't touch price. Advertising, better images, a stronger title and bundles all lift sales without going near your reference price.

A quick word on the panic

Some sellers read the 2026 changes and pulled every promotion they had. Don't. A product that never discounts can lose ground to competitors who use deals well. The goal isn't zero promotions. It's using the right type of promotion, and keeping your everyday price honest.

Get that balance right and the 2026 rules barely touch you. Drift into a permanent "sale price" and you can quietly lower the perceived value of a product you spent years building — and it's slow to win back.

A quick caveat: Amazon's rules on this are detailed and do change, so check the current guidance in Seller Central before you plan a big promotional calendar.

Auditing your pricing history, hunting down zombie sale prices and planning promotions so they don't backfire is fiddly, ongoing work.
