I've generally been a defender of the USPS, especially their extremely reliable delivery service for packages not susceptible to damage. But, I've come across a few inexplicable issues lately.
1) First class postage - Unless I'm missing something - and I've looked hard a couple of different times - it seems one can no longer purchase first class postage on packages through the USPS website. It's either well-hidden or simply not there, and if it's not there it seems unethical not to offer it for sale online. You can buy it online from third party sellers, but why put an obstacle in the way of purchasing it through USPS, other than the obvious reason, that you then either have to pay for priority mail or face the often long lines at the post office or use a third party seller.
2) Routing of mail - I've noticed a couple of times before that my packages have been routed strangely - like going from Chicago to Minneapolis via Warrenville/Pittsburgh (500 miles to the east to reach a destination 500 miles to the northwest, for those unfamiliar with U.S. geography). I think I read recently that USPS closed some distribution centers to try to save money, so I figured this might be the result. But a couple of weeks ago I shipped a package to a Chicago address a couple of miles from my post office, and THAT went through Warrenville - effectively turning a 2-mile trip into a 1000-mile trip. Certainly with the technology available today that cannot be the way a local delivery is supposed to work - I hope.
