UPS twice misdelivered my stuff to my neighbor last summer. I'm guessing the regular driver was on vacation because my house is located such that you almost have to really try to mess it up.
Based on that and the fact that I was at the end of their route and sometimes didn't get stuff I was anxiously awaiting until 8:30 PM, I signed up for their "My Choice" thingy and I now just have them keep my packages at their nearby location where I can pick them up at my leisure and don't have to worry about stuff being misdelivered, stolen or left out in the hot/rain/cold. I also get notified automatically when stuff ships and tracking updates.
I've also had problems with Fed Ex sometimes, and they have a similar service I now use.
