i recently purchased a firearm through an online auction sight. When the seller went to UPS he told them he was shipping a firearm. They then told that all firearms are sent requiring a signature at the other end. The ffl I was using is a private residence on a busy street. And the gun was left (by UPS) on his doorstep. This has been an ongoing problem for my ffl. I learned from another seller that UPS charges $5.50 to require signature upon delivery and that unless you request it and pay the fee, no matter what they tell you, your package (firearm) will be left on the doorstep like any other package.
