My son wants Minecraft pocket edition on Windows Phone for his birthday. Currently on the "My Family" settings on Windows Phone website I have his account set up to allow free downloads only.
I'm wondering what the best way to buy just this one app for him. I couldn't find any good documentation on this online.
If I change his account to allow paid downloads, will I have to link my credit card details to his account in order to buy the app for him? And if so will that mean he could end up making in-app purchases / more store purchases using my money?
