I had a weird one yesterday. The delivery confirmation info said that they had made a delivery attempt, and would retry the next day.
I too was sitting perhaps 10-15 feet from the door. The odd parts:
1) The package in question didn't require a signature.
2) I have a mailbox, and the package fits in the mailbox.
3) I never heard so much as a tap at the door.
4) The package was in the mailbox.
I need to learn to leave a note on my door:
"Dear delivery driver: I am at home awaiting your delivery. Please ring the door bell and wait for me to answer".
Or, "Yes I know your job isn't exactly the greatest thing in the world. But it's your job, so do it."
Then he will pee on your lawn.
At least they are intact.
United Package Smashers delivers to the right address, but some assembly may be required.
Note that I rarely have had an issue with either one, but I did get a box with a head-sized hole in it delivered by UPS once
Usually. A package of mine experienced a delivery attempt almost 400 miles away in a different state. I first suspected that something was amiss when the package was "out for delivery" quite a long ways from the local distribution center.
