If you are "self fulfilled Prime" i.e. your own warehouse...you must use Amazon negotiated rates and print Amazon labels. We do this. I would expect them to open their shipping service to us for this. It will put mail consolidators like Newgistics out of business. Newgistics picks up from us, sorts, then delivers to the nearest end point (Bulk Mail Processing Center), where USPS takes possession of the mail and delivers it "last mile".
