Agreed. I used to have a secondary procesor and made a FUCK of a lot of money on them (as much as a 20% boost in sales) until they went out of business. I always used a cookie for affiliates though, and blocked the secondary processor in that case, no sense telling affiliates to go fuck themselves.
What you don't see though is a lot of sites use ccbill's decline feature to push the secondary only on declines. Unless you actually sign up AND get declined you would never know. I think a lot of people overlook that one though as it was a lost sale anyway...
