Had a look and it seems that Google do refund the transaction fee, which I think adds weight to the argument that is unfair behaviour by Apple: https://support.google.com/googleplay/android-developer/answ... "Google will return the transaction fee to you. You'll see the returned transaction fee on your next earnings report."
"which I think adds weight to the argument that is unfair behaviour by Apple" Apple takes back from the developer exactly what they gave the developer. This has been verified by a number of people, and this submission is just farcically wrong. How is this nonsense front page on HN? Is this community this clueless?
If you charge $10, you get paid $7, and if the customer refunds, Apple removes $10 from your account – you'll be $3 worse off than if the customer never purchased anything.
