Up here in Wyoming, all of our USPS stuff has to clear thru Denver. My "cell mate" here at work had his daughter send up some documents for him to sign from Amarillo via 2-Day Priority Mail. She handed it to the post office to get it started on it's journey on a Friday morning, so "2-Days" should have put that envelope in his hands no later than Tuesday afternoon. It took a day to get from Denver to Cheyenne according to the Tracking, another day to get from Cheyenne out to the local post office, and the package went out for delivery the following day.
Thursday. When 2-Day priority mail was paid for it to arrive on Monday, Tuesday at the latest.
Myself, I have a couple of packages that are supposedly in transit from an Amazon vendor. One was supposed to have arrived last Friday. The other supposedly got here yesterday. I have neither, and have started Amazon looking into the situation as of last night. More to come on this front, I'm sure...
