No paypal yet? grml
I´m a direct debit fan. Hope they put this in (either directly or by paypal), nothing easier than paying that way (at least in germany ;) ).
edit:
What also would be an idea is to put in a list of payment options on the HP on a easy to see & easy to get to place. Since I have not found something I assume its made the "casual" way. That is, after you have selected the games you want, typed in all data needed and then as very last step have payment options. If, after all this, the one you have is not listet its annoying. :)
