I can not remember the last time I have had to sign anything for UPS and FedEx. I have had them leave 500 rounds of ammo on my doorstep with no signature needed. They do not even knock or ring the doorbell anymore. The dog tells me when the trucks pull up and someone walks near the house!
Actually, yes. That's who, if given the choice, I always ask for my stuff to be shipped by. With USPS my packages are always there when I get home, no signing and sticking, no having to go pick it up, no hassles, no problems.
