Say your selling a 1 item purchase like an ebook. Then how do you display your payment options? Should you sort of force one option on the buyer, ie: PayPal, then maybe have a link to other payment options.
Or should you display all the payment options and allow them to select for themselves?
Interesting idea...but one that seems to be open to abuse.
