Amazons in a weird boat. Like building a marketplace where they are the most dominant player and they favor themselves. But I guess that’s how supermarkets are too. I buy Krogers brands because I know they'll be vetted and meet a certain bar. If I don’t like it, I can always return it for a refund. It’s not great for competition and Amazon can easily boost crappy cheap products. Amazon is a massive beast. What is the alternative with better experience ?
