The secret to Fedex logistics is the use of "hubs". Things don't just get picked up and delivered directly to you. They always hit a hub, get organized, and then go back out for delivery. Of course this makes total sense when things are covering great distances, but seems a little backward when it seems it would be easier to just shoot over and pick something up that is so close!
If you're really bored while waiting for your computer, there is tons of information on this stuff out there:
The Spoke-hub distribution paradigm (also known as a hub and spoke model) derives its name from a bicycle wheel, which consists of a number of spokes jutting outward from a central hub. In the abstract sense, a location is selected to be a hub, and the paths that lead from points of origin and destination are considered spokes. Because of the efficiency (and relative inflexibility) of the model, it requires that the items (or people) being distributed must be routed through a central hub before reaching their destination.
Two industries that make use of this model are transport and freight.
FedEx founder Fred Smith pioneered the hub and spoke model for overnight package delivery in the mid-1970s. Smith established his company's hub at Memphis International Airport (Memphis, Tennessee). Soon after, other firms like UPS and Airborne had no choice but to develop their own hub and spoke model given the natural superiority of this system for speedy delivery of packages. In addition to FedEx, Delta Air Lines pioneered the hub and spoke system in the passenger transportation industry at its hub in Atlanta, Georgia to compete with Eastern Air Lines.
