Amazon also recently published the following job posting on its site:
Amazon is growing at a faster speed than UPS and FedEx, who are responsible for shipping the majority of our packages. At this rate Amazon cannot continue to rely solely on the solutions provided through traditional logistics providers. To do so will limit our growth, increase costs and impede innovation in delivery capabilities. Last Mile is the solution to this. It is a program which is going to revolutionize how shipments are delivered to millions of customers.
