Amazon has done some stuff that smells anti-competitive. For example... where did all the product listings go from this sellers profile? (https://www.amazon.com/gp/node/index.html?ie=UTF8&me=A2RFSIF...) They seem to have all disappeared the day after thanksgiving last year....

I heard through the grapevine that in the marketplace agreement, that you must list all products from all channels you have a presence in with the amazon channel to stay in compliance.

why would they do that? Oh probably because Ma Bell uses that data to target which products they want to compete in from their eCommerce company.
