Ah, 33cents a check... I can dream. I'm paying A$6, and that's the cheapest rate at present
But self pitying moans aside LOL... Greenguy is right about the eggs in one basket.
To be honest I think choosing sponsors based solely on their processor is not the best way to do business. You're better off making decisions based on
a. How much you get paid
b. Whether they convert
c. Whether the site has a decent members area and can retain members
d. If it caters to your niche
In terms of just getting one check... if you're looking to cut costs there you just up the minimum payment amount.
