I don't think they have enough power to dictate that kind of deal on the Internet. It's too easy for merchants to re-organize around another platform if needed

I don't think they have enough power to dictate that kind of deal on the Internet. It's too easy for merchants to re-organize around another platform if needed. Amazon wouldn't lose all customers to that service, but they would no longer be the only place that one buys stuff, which is pretty close to what they are now. Going membership-only would simply leave too much money on the table for it to not be picked up by others. Ebay I think would be ready to pick up the slack, if nobody else.
