Amazon is rolling out significant changes to its reference pricing policies, marking a major shift in how third-party sellers can advertise discounts on its platform. Beginning April 23, 2026, the e-commerce giant will enforce stricter validation rules for List Price claims, requiring sellers to substantiate these prices with verifiable data. A second wave of changes, affecting the calculation of Typical Price, will take effect on May 18, 2026.
Stricter Rules for List Price Validation
As of April 23, sellers listing products on Amazon will need to adhere to new criteria for their List Price – commonly referred to as the Manufacturer’s Suggested Retail Price. To meet Amazon’s updated requirements, a List Price must fulfill one of two conditions: either the product must have been sold at that price by another retailer within a recent timeframe, or it must have been purchased on Amazon as the Featured Offer at the same price. Sellers must provide external evidence for verification, as Amazon will no longer rely solely on their assertions.
This change could have a substantial impact on sellers who previously used inflated List Prices to display larger discount percentages. Amazon has made it clear that a List Price failing to meet these criteria will not generate a strike-through display or any associated savings amount for shoppers.

Changes to Typical Price Calculation
The second phase of Amazon’s pricing policy updates focuses on the Typical Price calculation, which determines whether a product is eligible to display a strike-through price. Under current rules, Typical Price reflects the median non-promotional price customers paid for a product over the past 90 days, excluding promotional sales. However, starting May 18, this exclusion will no longer apply automatically.
If a product’s Featured Offer price is below its non-promotional median for more than half of a 90-day period, Amazon will include all sales – promotional and non-promotional – in its Typical Price calculation. As a result, sellers running prolonged discounts or price campaigns for more than 45 days within the 90-day window may see their Typical Price recalibrated downward, potentially eliminating the strike-through pricing used to attract customers.
Amazon has also clarified that discounts not explicitly advertised as promotions, such as those applied through seller-side tools, will now be treated as non-promotional sales and factored into the Typical Price calculation.
Impact on Sellers and Advertising Strategies
These updates have sparked significant reactions within Amazon’s seller community. Mason Merhoff, an experienced seller and founder of ProvenPrice, described the implications in a LinkedIn post, stating, "Your past pricing behavior determines your future conversion." He warned that sellers heavily reliant on persistent discounts may lose the conversion lift associated with visible strike-through pricing.
Hadia Arif, a PPC growth strategist, added that the changes could affect advertising performance. "The listings with ‘always on’ coupons show 15-20% lower conversion once the coupon is stripped vs a clean static price", she explained. According to Mark Calvo, the new rules may also create challenges for sellers of seasonal products, as consistent pricing before peak seasons is now crucial to maintaining deal pricing eligibility.
Some sellers have tied the updates to broader shifts in Amazon’s platform strategy. Carlos Caparros Guerrero suggested that Amazon may be prioritizing price stability as a signal for brand authority, stating, "Price stability is becoming the new proxy for brand authority in Amazon’s eyes."
Aligning Policies with Transparency Tools
Amazon has linked these reference pricing updates to its Price History Graph, which is visible on product detail pages. The graph records the lowest Featured Offer price each day, offering shoppers a transparent view of a product’s pricing history. According to Amazon’s email to sellers, the updates will "align reference pricing across our store with information shown in the Price History Graph." Effectively, the graph will now serve as an enforcement mechanism for the new policies, ensuring that displayed reference prices accurately reflect historical sales data.
Key Dates to Remember
Here is the timeline for the changes:
- April 23, 2026: New List Price validation rules take effect. Sellers must substantiate List Prices with verifiable data from third-party retailers or Amazon transaction history.
- May 18, 2026: Updated Typical Price calculation rules go live. Promotional prices will be included in the calculation if they represent the majority of the product’s 90-day pricing history.
- Rolling 90-Day Window: Sellers who stop discounting on May 18 will need approximately 90 days to restore standard exclusion logic for Typical Price calculations.
Challenges Ahead for Sellers
The updated rules may pose operational hurdles for sellers. For example, those who rely on Amazon’s Price Discounts tool – a feature requiring minimum discount thresholds and a clean 30-day price history – might see their campaigns suppressed if reference prices fail validation. Amazon’s documentation warns that an invalid List Price will prevent strike-through pricing from appearing, which could make promotional efforts less effective.
Moreover, sellers who run price discounts for extended periods might struggle to adapt under the new framework. As Amazon notes, discounts are validated daily, and campaigns can be invalidated mid-run if reference prices change or eligibility criteria are no longer met.
Conclusion
Amazon’s updated pricing rules are designed to enhance customer trust by ensuring that all discounts presented on its platform are genuine and verifiable. These changes, while aimed at transparency, represent a significant shift for sellers who have relied on flexible pricing strategies to boost conversions. With deadlines approaching in April and May, sellers will need to carefully reassess their pricing models and promotional strategies to remain compliant and competitive in Amazon’s marketplace. As Carlos Caparros Guerrero aptly noted, "Price stability is becoming the new proxy for brand authority in Amazon’s eyes."
