General delivery yes. But for overnighting letters and small packages P2P, B2P, or P2B? Not a market that Amazon is in ......YET!!!!
@catfish1957 It IS a market the Post Office was in long before any of the others even existed.
In fact,they are always my first choice if the seller will ship by USPS.
One reason is I never have to worry about my package being left on the steps in the rain if I am not home when it is delivered. It's put inside my enclosed porch. It has been several years now,and neither Fed Ex or UPS can seem to manage something as complicated as a door knob.
Plus,one day I cut open and reached into a package that had been sitting outside for most of the day,and there was a freaking snake inside it. Not a big one,maybe 10-12 inches long before I mashed him into mush with a 20 ounce ball peen hammer,but a copperhead doesn't have to be big to be deadly.
