Hi Dave,
I checked with Casino Blasters and their minimum payment is $50. The affiliate support staff at the other two affiliate programs that you mentioned were unavailable, and there was no minimum payment indicated on their sites.
We implemented a minimum payment because we absorb all the transaction costs incuding Neteller, PaySpark, wires, ACHs, etc. A minimum payout of $5 (to use your example) does not make financial sense when we incur a $7-$8 cost on a mail check.
We based this amount on the industry average, however, we are in the process of restructuring and rebranding and will be upgrading to a completely new website at the beginning of September. I will discuss this point with our Finance department in an attempt to lower the minimum payout.
Regards,
Yashin
