Mine isn't going through either. And I don't have a PO box and live in the States. Must be a snag in the software somewhere. I purchased something okay about 24 hours ago, but didn't get an email receipt which is really strange. First time that's happened. BTW..obviously not my real name there. I change it whenever I do an order, and yes, it was correct. Tried a few times (select my name from my browser dropdown for accuracy). Even shut down the browser and tried again later.
