They already do this. There are postal counters that are contracted out. I went to one in LA's Koreatown. It was croweded but OK, and was a little faster than the perpetually understaffed USPS windows in Pico Union. (It's often 5+ people in line, and one clerk.)
They took their large sorting facility property, Terminal Annex, and leased it to a server colocation company. It's at 900 Alameda, Los Angeles. Look it up.
They stil have PO Boxes and a counter there. I recently tried to drop off a letter there on the weekend, but THERE WAS NO FREAKING MAILBOX. USPS needs to stop eliminating mailboxes. There are even post offices without mailboxes outside. Do they not want to make money?
rather than partnering with convenience stores like in Europe?
As others have pointed out, they already do. Go to http://www.usps.com and click on "Find Locations." Put in your zip code, click on "See More Results" and sort by "Approved Postal Providers" to find those non-USPS-owned locations.
Post Offices in small towns were often located in other businesses, like a Starbucks in a supermarket, although they may have all been closed by now as a cost cutting move.
