Amazon Tightens Reference Pricing Rules: What Sellers Must Know
Amazon has updated the rules around how reference prices are validated across its stores, and the changes are significant enough that sellers who rely on Was Price and RRP displays to drive conversions need to act now. The UK changes came into effect in June 2026, Germany follows in September, and other EU markets are expected to be brought in line shortly after.
The practical consequence for sellers who do not meet the new requirements is straightforward. Your reference price simply will not show. No Was Price. No RRP. Just the selling price, with nothing for buyers to compare it against.
Why Amazon Is Making These Changes
The changes are connected to a price history graph Amazon recently launched on Rufus, which shows buyers the lowest Featured Offer price for a product on each day over the past 90 days. Amazon wants the reference prices displayed on listings to be consistent with what buyers can see on that graph, which means sellers can no longer display an RRP or Was Price that is not genuinely supported by real pricing history.
The direction of travel here is straightforward. Amazon is trying to make sure that when a buyer sees a discount, it reflects something real rather than an artificially inflated starting point that was never a genuine market price.
What Has Changed for RRP
An RRP now needs to be substantiated by one of two things. Either the product was genuinely sold at that price on Amazon as the Featured Offer, or it was verifiably available at that price at another retailer recently. An RRP that cannot be supported by either of those will be suppressed from the listing.
From September 2026 in Germany and other EU stores, Amazon is adding a further condition. Sales at the RRP on Amazon only count toward validation if the offer was also showing as the Featured Offer on the price history graph for a meaningful number of days during that period. Simply having sold at the RRP at some point is no longer enough on its own.
The margin of tolerance is narrow. A product priced significantly above its stated RRP does not validate the reference price, even if the seller believes the RRP is accurate. The price needs to be at or very close to the RRP to count.
What Has Changed for Was Price
Was Price has historically been calculated using non-promotional sales only, which gave sellers the ability to establish a higher baseline by keeping prices elevated outside of promotional periods. That calculation has now changed.
If a product has spent more than half of its 90-day price history below the non-promotional median price, Amazon will now include promotional sales in the Was Price calculation. The effect is that sellers who run deep or frequent discounts will see their Was Price baseline pulled downward, making it harder to show large savings against a high reference price.
Prices that are reduced without being explicitly labelled as promotions are also now treated as standard sales and factored into the calculation, which closes off an approach some sellers used to quietly lower prices without affecting their official promotional pricing history.
What Sellers Should Do
The first step is a straightforward audit of current RRPs across the catalogue, specifically looking for any that are not supported by genuine Featured Offer sales history on Amazon or verifiable retail pricing elsewhere. Any that cannot be substantiated should be reviewed before they are suppressed automatically.
For sellers running regular promotions, it is worth looking at the balance between promotional and non-promotional days over the past 90 days for key products, since the new Was Price calculation will affect any product where promotional pricing has dominated the price history. The 90-day lookback period means the impact of recent pricing decisions will already be baked into the calculation, so this is worth checking now rather than waiting to see the effect on listings.
