I'm receiving a UPS Next Day Air package, and while their should be someone there to sign for it, they may be temporarily disposed at one point (like my wife for 5-10 minutes feeding my infant daughter) . Can I just leave a note saying to leave the package at the door (behind an object), which she'll be able to get with 5-10 minutes), and/or even leave an advance signature on the door as a backup. Packages get left in front of doors all the time here and theft is a non-issue. The other option is paying 40 for UPS My Choice Premium (which is actually pretty nice, even the free version which sometimes sends me notices even before companies send tracking info), which allows you to select a 2hr time frame and instructions for the driver (and could be used for other packages).
