"UPS makes up to three delivery attempts, excluding weekends and holidays. The third and final delivery attempt has been made, and the driver was unable to leave your package. UPS reserves the right to return the package to the shipper after three delivery attempts."
Also, you can pre-sign packages or schedule to pick it up at a UPS facility.
I didn't know about pre-signing to be honest, but they didn't do the 3 attempts, which is what angered me. I looked at the sheet, and when I called after the first attempt, they said they already sent it back.
