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.
I'm not joking, this is exactly what they have done (and keep doing) with "partners". Amazon is all but transparent and it has been growing like crazy during the last 6-8 years thanks to this exact strategy. Online is not enough anymore, they need to conquer local stores as well. The empire strikes back.
