On the flip side, the UPS store in town has been a pain in the balls to deal with so much that I don't use them anymore. If you must, use a UPS hub to ship.
With the rules in place at FedEx and UPS now there is no more counter service for the shipment and delivery of firearms.
Doesn't matter if you have an FFL or not, you have to have an account with UPS or FedEx and they will only pick up the package at your business.
FedEx will no longer ship machine guns, UPS never did (in my span of memory)
If you ship a firearm or firearm related contraband (read 80% receiver to a place they are banned) via UPS or Fedex in violation of their rules and they discover it, the item will be destroyed and you will be banned from using their services.
Both carriers dumped Brownell's for shipping 80% lowers to states where those items are banned (when the AJ in NY sued Brownell's) so they are serious about these rules.
That also means you can't make a claim on lost or damaged firearms you ship in violation of their polices.
A UPS / FedEx store was never supposed to accept firearms over the counter as they are contractors and not allowed to store them.
I hope the USPS doesn't change their game and judging from what I read you better know the chapter and verse of their rules in case you get an idiot at the counter who says no to shipping long guns.
