I sent 5 carbs, set-up for Alcohol, via USPS to a guy about 5 states away. He never got them after 2 weeks. I checked the tracking # and it said it got delivered. I thought Oh, hell, someone got 5 Alky carbs that wasn't supposed to! So, I had my personal detective (WIFE) track it down.
Turned out, the post office where I shipped them from, transposed the last 2 #'s in the zip code and it was sent to a town about 20 miles from where it was to be delivered. What made me nervous was, both towns had the EXACT same address. Luckily, the post office where it was sent to, in the wrong town, noticed the town & zip code did not match, so they held it there, and even though the tracking # said it was delivered, it was being held. It was finally delivered to the right guy a couple days later. NO MORE USPS FOR ME....unless its something small and not worth a lot!
