It's a trap. You, owner of a shop, don't do this. Amazon will first analyze all your sales data, they will than attach reviews to your shop and finally they will oblige you to play by their rules or die (banned or killed by bad reviews) and either way they will grow thanks to your hard work.

At that point Amazon controls your cashflow and your products and--in a sense--owns your business.
