> over-price and they don’t sell anything Well, that depends on the service itself. I often buy from Amazon not because it's cheaper, but because I know that shipping will be quick, even if it's imported the charge won't be taken by the carrier with an absurdly high fee, that if something has to be returned it will be easy. I even usually avoid third-party sellers on Amazon because of that, even if they are much cheaper. > under-price and they leave money on the table You just said that overprice and they won't sell anything. Seems like the alternative isn't money on the table but nothing at all on the table. > if a company dominates, no one will challenge them I think that's the wrong part. If someone can do just as good or better than Amazon, they'll do it. Amazon is the proof itself, there's so many products that still have third party on Amazon itself that compete against Amazon. This option will just let Amazon have access to a bigger inventory for a lower cost than owning it themselves... That's not a huge advantage. I'm sure their algorithmns are already pretty good to balance the right amount of stock.
