Shipping outside of the US is a pain if you work full-time. The post offices around me open long after I'm already at work and close before I get out. There is one official post office around me that is open on Saturday morning, but you might as well hunker down for a good hour to wait in line.

The alternative is to go to a non-official postage place (Mailbox Etc, etc), but you will pay more for the convenience. I would love to know if there is a better way.
