I signed up for this service at Christmas time. I have had a few months to test drive it and I love it. Keep in mind, I am an online shopper, so it is nice to be notified when a box will arrive. I get an email from UPS letting me know what day and time a delivery is estimated. It really helps me plan, because I hate to leave packages by the door.
