No, unfortunately not. We cannot accept credit cards directly.
We used to be able to do that, but consistent fraud has made our payment provider kick us out (though we were paying all the horrendous fees for the chargebacks).
The only way you can pay with your credit card is via our payment providers. Credit cards are accepted by PayPal and Moneybookers, and you can use them to by cashU, Ukash and Liberty Reserve.
Or try www.xoom.com, they let you use your credit card to send bank wires (so you could choose "bank transfer" as the means of payment on our web page and use their service to complete it).
