I just went through having 2 packages missing. 1 sent by ups was special formulate medication for my back and the 2nd was from a local quilt show across town sent by post office. I had been talking to both about now receiving either one. Well I got luck because the pharmacy had put my phone number on the shipping label and the lady who had gotten my medication called to let me know she had it. She lives on 84th pl and I live on 86th pl, same house#. I meet her to get the package and went back home. As I pulled in the driveway she called again stating she had checked her mail box and had another package for me. The lesson that I learned from this is to put either my phone# or the receipents phone# on the package as well. Or at the very least put something in the package with contact information in case it gets delivered to the wrong address.
