Does anyone know what the semantic difference is between an in-app purchase in Android, and selling a digital good via Google Wallet?
I can see that there is a big difference in the fee Google charges. In-app purchase fees are 30% of the amount charged. Google Wallet digital goods fees are less than 5%. Obviously, nobody in their right mind wants to pay 25% more than necessary.
I cannot find a text anywhere describing what the difference is as seen with Google's eyes. Does anyone have a link? Or an explanation?
