I have a business where i get paid by Prepaid Cards by the clients. I need a way to accept it without giving out my big margins out of my sale amount. Right now, i am paying 15% to a guy who let me charge through his Merchant gateway. The best thing is, these don't have a Charge-Back issue plus the guy pays me everyday 85% of what i charge through his gateway. Any solution i can charge them myself and save money ?
