But, be careful about "signature required" deliveries. I'm not all that certain that either UPS or FedEx will necessarily attempt to give the package to a neighbor; they may take it back with them and try again another day!
I recently was sent a "signature required" package. Fortunately, I had the tracking number so I could see where the package was. The dilemma was that "expected delivery" was on a certain Friday. My calendar was very cluttered that day, but I cancelled two things so as to be at home.
Yes, I might have said, "Oh, well, they'll bring it Monday." BUT, I was going to be out of town all day Monday!
Bottom line: they came Friday, but well after 5:00pm, and my optional event at 6:00 wasn't doable anymore!
