This bit of tracking information pretty much sums up why I hate the USPS sometimes:

Date                   Time                 Location               Checkpoint Details
May 23, 2008     10:42:00 PM     MEMPHIS TN         SHIPMENT HAS LEFT SELLER FACILITY AND IS IN TRANSIT

Ship Method:      USPS
Status:     IN TRANSIT
Shipment Date:     May 23, 2008
Destination:     Nashville, TN, United States
Estimated Arrival:     Jul 14, 2008

Really? Are they WALKING it here from Memphis?
