If you’re set on using clickbank… well this is one of the limitations clickbank has. The only way I can really think to do it is to set up 2 separate clickbank accounts for the same product. Put your standard payout in the marketplace and not to list your higher percentage payout, instead inform your VIP affiliates of the second program manually.

That’s actually not a very good solution, because your VIP affiliates are going to push your product up in the marketplace, so not listing your best selling product is a poor idea. However if you list the higher program everyone is going to promote that higher payout program and there really would be no point to having the other standard program.

I don’t really think there is a feasible way of having 2 different payouts for a clickbank product.
