Amazon has a long term deal with the USPS. They will deliver to the customer. The last mile is very, very expensive, just as the last mile of data for internet/tv/phone, etc. Amazon will deliver directly to the closest post office, via truck, and the USPS will deliver it to the door.
20-25 planes, other sources say the plan is 60, while others state it is to be larger than FedEx or UPS, as far as Domestic packages. I wonder about international?
