And now for another USPS plug ;)
Last week when my new laser and related equipment arrived wired for European 220v, I ordered a 3000w step-up/down transformer so I could run the thing. It was shipped FedEx on Monday. Tracking said it would be delivered Thursday (today). Yesterday I received a recorded message from FedEx saying it would be delivered today. At 3pm I ran tracking, it arrived at the FedEx office in town, 6 miles away, at a little after 1pm.
It's now 10:15pm and FedEx has yet to deliver my transformer...
The USPS isn't perfect, but they're cheaper, faster, and in the long run I've had better results with them.
