So during the SNAFU last week, I actually managed to create an account, I could just never get to the billing/ordering step. When I tried it with the existing account today (only tested in Chrome), I still got stuck in the same selection-page-reloading limbo.
However, I opened up IE (to be safe) and created a new account, and then it worked fine.
Code BFBLOG worked for me, too. Paid $19.99.
Also, in case anyone was wondering (like me): when you first go to input your name etc., the address it prompts you with is your shipping address. You won't have a chance to enter a different shipping address, but you can enter a different billing address. I wish they had clarified that on the first step.
