Amazon's Price Parity S-4 Seller Term Has Changed

March 13, 2019

Amazon's Price Parity S-4 Seller Term has changed. This means that sellers can list lower on other marketplace sites or DTC sites than they do on Amazon and not be punished with ASIN suppressions or account suspensions. Below screenshot of the old verbiage where Amazon required sellers to offer their products in price parity to their listings on other retailers. That clause is now removed.

Amazon's Price Parity S-4 Seller Term Has Changed, removing this S-4 clause that stated how Amazon required sellers to offer their products at price parity to other retailers.

Key questions regarding the change include the following:

‍Is Amazon still going to price match? Yes. This policy only affects third-party sellers and their decision of whether or not to keep pricing consistent between Amazon and other selling platforms.

‍Is Amazon still going to suppress Buy Box for non-competitive products? Yes. Although the S-4 clause has been eliminated, this does not seem to affect Amazon’s algorithm for Buy Box suppression. That algorithm compares current Amazon pricing to other marketplaces, which is indifferent to individual sellers. Therefore, the suppression will take place regardless of whether or not the lower price is being offered by a specific Amazon seller.

‍Is Amazon expecting sellers to offer their products at the lowest price on Amazon vs. eBay, Google, Walmart or other channels? No. Amazon will no longer monitor sellers’ other selling channels to enforce the lowest pricing on the Amazon platform. Below is the policy as it currently stands.
