No expert to be sure but will chime in on the original question.

CCBill also has a cascade billing option allowing surfers from other countries or bad credit history with CCBill to use alternate processors. The system is set up through CCBill so that affiliates are tracked and paid by CCBill regardless of who processes the sale.

As a budding affiliate, I like both NATS and CCBill sponsors due to reliable and flexible stats. As Luke said, the programs that tend to use NATS also have a better rep on many of the forums. Especially when it comes to on time payments and skimming. Who knows why?

I tend to promote mostly CCBill sponsors only because I'm small and can combine all my sponsor's sales together to obtain a weekly check. For the whales, a $500 minimum may be nothing but to a guy like me, hitting a $500 threshold for some sites would mean I virtually never get paid. I also like the NATS sponsors that have many sites with affiliate content in their program for the same reason. A few sales here and there adds up.
