Shipped large 3 boxes (Xmas presents) to my sister. Driver left them on front porch of WRONG ADDRESS. (Don't they use GPS?) Never knocked or rang doorbell. Neighbor's daughter happened to come outside hours later and nearly tripped over the boxes, then realized they were mis-delivered. She called my sister who came over and carried the boxes home. Had this neighbor not been honest, it would have been a total loss. UPS says oops, we're sorry, we'll talk to our driver, but he recorded that he left them at the correct address.
NEVER USE UPS!
