Annoyed with USPS

Over the weekend, DH and I finished the TY's. Our local P.O. didn't have the wedding stamps so I ordered them on-line through USPS. I got an email on Monday saying they'd been mailed. On Wednesday, I checked my account and it noted the order was 'completed.' The last time I ordered stamps on-line, it only took 2 days to receive them. They're not here yet! It's annoying me b/c the TYs are just sitting on my desk; half have stamps but the others don't. I just want to mail them and be done with them already!

Sorry, just had to vent!
