I am in the middle of an eBay transaction for which I paid $390 for an item a month ago and have not yet received it. My main beef is with the deadbeat seller, of course, but the U.S. Postal Service isn't making things any better. The seller on Friday finally gave me a tracking number for the package, but didn't mention which carrier he used. So I went online to UPS, Fedex, and the USPS to check them all. The problem is that while UPS and Fedex (and I'm sure every other carrier) tell you if the number is invalid, the USPS gives the same message for ANY number entered: "Tracking Service has not been purchased for this item." So I have no idea whether the number he gave me is legit or if I'm entering it in the wrong format. If I type VB247959386US or 11111, it's same message. At least with the other carriers, typing in 11111 gets you a warning that the number isn't even a valid tracking number! What kind of friggin' idiot designed the USPS's website tracking?
