Can't buy game?

I clicked on the “collector’s edition” and pressed buy, all that came up was the item in the cart, and the payment method. It gave me no options to do anything else except for using paypal, but when I clicked that it said no e-mail address was provided. Then when I clicked on the delete item from cart button, it brought up the fields to make the payment, but with nothing in the cart. I’ve never found buying something to be so difficult. x.X

Hi, payment method is a drop down box, you can select credit card, or any other option. Are you still having problems?
