Im wondering if anyone knows of a shopping cart that can be integrated with the CCBill affiliate system?

Im currently using WebmasterCart and have been told its 'almost' possible but only with single digit sales totals, im actually looking to sell various items at various price points that the end-user can select at will so the sales total will never be a fixed price on every transaction.

Does anyone know if..

1) Such a cart system exists and;
2) If no cart system exists, if there is another way to offer single item digital downloads via CCBill?

Regards,

Lee
