When you "spend" Google Play Credits in an app, Google Play treats those credits the same as if you paid with real money: they took 30% (their take isn't so steep today), I took 10%, and then I sent the user/buyer the remaining 60% directly from my bank account (I used Dwolla back then).
It was risky because I didn't actually receive any money from Google until about a month later.
