Here is something that I didn't know:
UPS stores are separate entities, and they all have their own rules on shipping guns. Went to one in anchorage, and they said I had to drive all the way out to the one at the airport to ship guns back to the manufacturer. That's about half an hour out of my way, both ways! So when I got to Wasilla, asked them about it, and they said yeah they ship them, and that some don't, cause they are owned by different people. Glad I figured that one out... so even with UPS, make sure you call the store first to make sure they ship guns.
