Wayne is correct in that USPS does offer a pretty low bufget service that is, for the most part, reliable. As far as I know, I've never not received a letter or package as a result of an error on the part of USPS. Regarding their tracking system, USPS's current tracking system does not provide real-time tracking like the other couriers, although I'd expect that sometime in the future. Consdering the volume of mail that they process, the huge customer base that they serve and the fact that (unfortunately) they are a quasi-government organization, they do a pretty effective job.
