If it doesn't show up, call UPS. They can tell by GPS where it was actually delivered to. This happened to me about a year ago. Package said it was delivered, it wasn't. I call and they tell me the standard "did you check with your neighbors"? Yada, yada. After a few days of calling and explaining that no one around me had it and it hadn't showed up, they traced the driver who had actually delivered it to a house a few streets over. The driver then went to this house to try and get the package and no one was home. He then came to tell me and that they would work to get it back. About an hour later I notice a mini-van in front of my house. Not until I go to the door does anyone get out and then she says she has my package. Ummm...you just never noticed it for a week? It wasn't opened so I don't know why she waited a week. It was just scrapbooks so it wasn't anything you could make money off of!!
