When I shipped a rifle to Kirby a couple years ago, the UPS driver who picked it up at my business tried to tell me that it was against policy. I promptly sat him down at a computer and pulled up the UPS website and showed him his own company's policy. A bit red faced, he took the package and everything was fine. I did declare it as a rifle simply for insurance purposes.
Everything I ship is 'tractor parts', even my kids Christmas presents as I feel its none of their darn business whats in the box as long as I pay for it. I've shipped rifles, parts, brass, bullets, and barbie dolls all as tractor parts. Its a MYOB kinda thing.
If any of you would like to me set up a UPS account please email at firstname.lastname@example.org This will cure the problems that some of seem to be having at the UPS shipping outlets. I will need your name, address and phone number. It is free service you aren't charge till you ship, and you will receive a bill in the mail. Plus I get some credits on my Ups card. When I set up an account for you, you receive a care packet in about 3 days with instructions and a few shipping labels. You can call after that, and they will send you pre-printed labels with your name, and shipper number, again free of charge. Don't let a few bad apples ruin your experience with your shipping rights.
