There are a couple of advantages to using CCBill. (1) Affiliates like it and many won’t sign up with non-CCBill sponsors. (2) I’m not familiar with iDev, but I’m assuming I have to hit some kind of a minimum to get paid by you; whereas if you were with CCBill, I just have to hit a $50 minimum for all my CCBill progs combined to get a cheque. So I could make one sale for your site this week, and as long as I make $50 in commission from any other or others on CCBill, I’ll get my commission for your sale within a week or two. Using programs that don’t use CCBill means that I can have lots of bits of money tied up here and there, and some of that money I’ll never get because the program just doesn’t sell or I decided not to sell it anymore.
