alt Hacker Newsthis is not related to AWS, but merely to amazon's retail business and their sellers know and sign up for the deal when they sell via amazon.
every single retail company does this, they allow suppliers to sell the product using retails's infrastructure, and then retailer turns around and create private label products using sales data (Costco's Kirkland Signature, Walmart's Great Value, are just some examples)
Yes, but Kirkland's signature comes from the same factory. If I'm the factory owner and Costco vis going to guarantee me sales albeit at a slightly lower margin, so long as I slap a different sticker on it, that's different than from Amazon finding out which of my products sells best and then gets someone else to rip it off so I don't get paid anything.
