Experience with USPS Parcel Tracking?

First call the local post office to see where the package is and let them know it wasn't delivered.

That's what I'm doing now with one package. It was supposed to be delivered to Phila (10 miles away) on July 14th... It's not there. The Post Office where I sent it from is calling the distribution center (last scanned location) to see what's going on...
