its kind of backwards. they charge you NOT to deliver. you pay for the storage of course. but delivery isn't cheap. its mandated by law though so they can't change it easily or even stop Saturday delivery without an act of Congress (for real) But, even so, the PO box is tied to a city. people can't keep using it and have mail go to the right place automatically. the best they can do is forward it. so something could be shipped from nyc to a PO box in LA and then get forwarded back
