I try to take it in perspective & give USPS credit sometimes. I know their stamp prices just went up, but where else can I have a birthday card, for instance, picked up from my mail box, carried clear across the country & put in my sister's mailbox a couple days later, all for 73 cents?
But I know how you feel about USPS tracking. I don't pretend to understand the mechanics of it, but it's funny how a package can pass right by my house on it's way to a distribution center 50 miles away, so it can be delivered two days later. I have to admit though, that our postal package delivery here is way better than UPS. For the last couple years, when I get a package delivered by UPS it's dirty, like it's been dragged across a warehouse floor, and beat all to hell & back. It used to be the other way around.
