I have a few 5$ visa gift cards. Is there a way to add them to my funds or stack them to buy a video? Or do all purchases need to be on one card?

I have not seen that option through ccbill. I wonder if you can use all those 5 dollar cards to fund 1 card and then toss the others.

Sorry, Epoch only allows one payment method at a time. They do Visa take gift cards tho.
