I’ve worked for Amazon. The thing you have to remember on the retail side is much of the focus is on CP (contribution profit) and much of analysis has to do with finding the largest negative CP products in different marketplaces and pulling levers to make them less negative. There’s a large number of negative CP items carried just because it improves customer selection which helps drive larger cart orders. I never heard of squeezing more profits out of already profitable products probably because positive CP is an indicator of a competitive price point.
