That's fine. What I was asking is how you can prove an on-line purchaser is the age they say they are? Make no mistake, 15% is not much (frankly I'm a bit concerned about the services you plan to provide for just that cut, considering simple order taking sites have a larger fee,) but please don't lie.
I don't think calling him a liar is helpful. And the developer does get 100% of the price that they want for the game. Frank simply adds 15% on top of that. Do you see?
