30% cheaper prices? Better user experience?
That's exactly my point. There are no real improvements I can see coming from any new store. Please explain how it will be better and why any actor would make it better.
In the emails linked, even Apple acknowledges that the 30% will be passed to the customers.
However, I have no reason to believe that Uber would actually follow through. It seemed like a bluff. Certainly, any economic theory I'm aware of would have Uber and customers split that 30%, with Uber paying the vast majority out of profits.
