In Amazon's "second price" auctions for ads on its platform, the winning bidder is supposed to only pay one cent more tha …
Pull your Amazon Search Term Report for the past 24 months -- if CPC rose faster than CVR, document it; this litigation may create refund or adjustment mechanisms for affected advertisers.
