Just read their press announcement. The bitcoin option isn't meant for users like you. This is for people who have trouble using CC and paypal.
Yep. I do not have a credit card, so I also can't have a paypal account. If I want to buy something online, I can either wire the money, or beg one of my friends to order it for me (or go to the bank and get a credit card, but I am way too lazy for that). Using bitcoin for me is a total no-brainer, and I'm sure I'm not the only having this problem.
