I've ran into that twice here in MN. The first time was at a UPS store and the lady almost had a heart attack just at the sight of the box. She couldn't get me out of the store fast enough. I had to go through an FFL. The second time I tried going to the UPS hub. That didn't work either. The only way she would send it was if I sent it directly to an FFL. And don't try to argue with her. She knew her job and knew the laws. I was fortunate enough that there was a small gun shop that had just opened in town and he shipped it for me for a $5 handling fee. Oddly enough it still turned out to be cheaper that way than what the UPS lady quoted to me.
