As far as I know you can't sell games on steam if you offer them cheaper somewhere else. So if you want to sell game for $20 it has to be $20 everywhere to sell it on steam. i.e. You can't charge more on steam to cover valve's cut.
Oh ok, i didn't knew that, that's great to know. Thanks
You can't sell steam keys outside of the steam store at a lower price than the advertised in the store.
