Apparently, not as much as it use too. The last thing that UPS wants to see. Amazon is building it's own pack it and deliver it service, otherwise known as Amazon Prime, which means less dependence on UPS and FedEx. Any increase of delivery control by Amazon means more leverage over the future price contracts between Amazon,UPS, and FedEx. I know, I know, and I know, the prevailing arrogance is that UPS and FedEx are the kings of parcel delivery and a pack and ship it company can't survive without using their services. Amazon is not your typical pack it and ship it company. In the world of pack it and ship it, Amazon is the 800lb gorilla pack it and ship it company. Amazon will continue to use UPS and FedEx but the day is coming when both companies are going to lose a substantial portion of their Amazon business revenue. it's coming, it's just a question of when and how much.
