Always request signature confirmation. It cos couple more dollars with UPS but it saved me thousands. Recently I had a guy asking to deliver product to different than billing address and to tell UPS to leave it behind storm door. I did not go for it. As it happens, UPS actually did not release package and requested to be signed by the person listed on the label. I guess whoever was there could not provide valid ID and this way UPS driver took the package back. Now they need to show up to pick it up with valid ID. Guess what? Noone did show up. I looked into the the order myself. And my god, UPS driver saved me almost $2000. I was so busy that I did not verify it before. Phone number was incorrect, order placed all with capital letters and of course next day air delivery. How could I miss that. Now I am waiting for shipment to be returned. Thank you UPS guy for right judgement.
