Court Certifies Class of eBay and Walmart Buyers in Amazon Price-Parity Case
A long-running antitrust case over how Amazon's pricing rules affect prices on other marketplaces has moved forward. In a redacted order made public on November 2, 2026, a federal judge in Seattle certified a class of eBay and Walmart Marketplace shoppers who say Amazon's policies pushed sellers to keep prices higher everywhere. For sellers who list the same products on several channels, the case is worth understanding.
This is a summary of a court proceeding, not legal advice. Nothing has been decided on the merits.
What the court decided
In Frame-Wilson et al. v. Amazon.com, Inc. (No. 2:20-cv-00424, W.D. Wash.), U.S. District Judge John H. Chun granted in part the plaintiffs' motion for class certification, according to the court's redacted order (dated Nov 2, 2026). The certified class is:
All persons who, on or after March 19, 2016, made in the United States at least two purchases from a third-party seller on the Walmart online retail marketplace or at least four purchases from a third-party seller on eBay of new, physical products concurrently offered for sale by that same third-party seller on Amazon Marketplace and monitored by Amazon as part of its competitive price monitoring.
The court narrowed the plaintiffs' proposed definition by requiring that the product be offered by "that same" third-party seller on Amazon. Plaintiffs estimated the proposed class at "at least 10 million consumers," the order notes. VitalLaw reports the court rejected Amazon's argument that the class would be unmanageable.
What the plaintiffs allege
The plaintiffs claim Amazon maintains an "anti-discounting policy," a kind of platform most-favored-nation restraint that discourages third-party sellers from offering lower prices on competing marketplaces, in violation of Sections 1 and 2 of the Sherman Act. The order describes several policies they point to:
- The Amazon Services Business Solutions Agreement and the policies it incorporates.
- The Marketplace Fair Pricing Policy.
- A 2021 clarification to the Seller Code of Conduct about off-Amazon incentives.
- The SC-FOD tool, which plaintiffs say can remove Featured Offer (Buy Box) eligibility when a lower price is found elsewhere.
The judge wrote that plaintiffs' evidence "suggests that Amazon operates under a general policy of price parity via its contractual agreements with sellers." Amazon disputes this. According to Value Added Resource (Nov 4, 2026), Amazon argues SC-FOD compares prices only against a limited set of established retailers, that sellers can regain eligibility by lowering their Amazon price without changing prices elsewhere, and that its policies are lawful and benefit consumers. Value Added Resource also reports Amazon is seeking permission to appeal the certification to the Ninth Circuit.

What it means for sellers (our analysis)
No immediate change to Amazon's rules. Class certification doesn't change any Amazon policy today. Amazon's Featured Offer and pricing tools work as before while the case continues.
Multichannel pricing is under a spotlight. Between this case and other government actions over Amazon's pricing policies, how Amazon treats lower prices elsewhere is being examined closely. Keep records of how and why you set prices on each channel.
Know the trade-off you face today. If your price is lower on Walmart or your own site, your Amazon offer may lose Featured Offer eligibility. Many sellers manage this by aligning prices or by differentiating bundles per channel, but there is no single right answer.
Fees shape prices. Plaintiffs argue Amazon's fees feed into prices across channels. Whatever the outcome, knowing your all-in fee rate per channel, as in our Amazon vs Walmart referral fees comparison, is the basis for any pricing decision.
Checklist for multichannel sellers
- Document your pricing logic for each marketplace.
- Monitor Featured Offer status on your top Amazon ASINs.
- Calculate the all-in fee rate per channel before matching prices.
- Consider channel-specific bundles where price matching is uneconomic.
- Follow the case for any appeal decision or settlement.
