Maybe -- but the advantages to Amazon are the differences from UPS and FedEx. For example, there are few sources -- the warehouses. If done right, there's no need to sort, the warehouse releases ready-to-go containers. And so on.
That would be nice - an alternative to the UPS FedEx duopoly. Maybe they can push the shipping rates lower than the evil twins set it at now. The two are doing about 100 billion in business, so it is a large market to go after.
I have been shipping daily with both of them for a decade; it would be nice to have another choice with national coverage.
I would hope that Amazon is introducing competition to UPS and FedEx - but its also possible that they are paving the way for a Vertically integrated Monopoly. Time will tell, I suppose.
