I agree sqezer. I've been through that several times. I figured out the UPS stores are worthless. I went to the UPS hub and the lady said it looked like it might be a gun in the box so she wouldn't ship it. I explained to her it wasn't - it was a muzzleloader. She insisted that was still a gun. She said the only way she would ship it is if I wanted to open the box, show her what was inside, and let her decide if it looked like a gun or not.
I won't ship through UPS anymore.
