I want to give my son an app the App Store. Since there's no option to gift apps, I was wondering if it's possible to log into the App Store as me on his computer, pay for and download the app. Afterwards of course I'd log out of my account. Is this possible, and does it break the terms of service in any way? I realise this means we'd have to cooperate whenever he needed to upgrade (not a problem), and I know I can get him an iTunes gift card so he can do it himself, but there are reasons I'd prefer to do it as I've described above. So all I'm looking for here is knowledge about whether it can be done, and if I'd be violating any terms by doing it this way.
