When you're new you only get 50%, that rate goes up when you earn more. I think my account is at 55% right now. But the numbers I mentioned in my post is what I get, not the total amount of sales we generate.
Huh, and here is another idea - build CodeCanyon clone but take 20% :)
Nowhere near the same amount of exposure. Yes, you'll earn a higher percentage, however with the lower number of sales, the money you pocket will be significantly less.
