I've been to the Purchase History but it only includes "purchases" from iTunes Store, the music, books, movies obvious stuff. It seems a right place to include the In App purchases but they are not there.
I did all the "turn off" stuff on my account. If I need to do it on every device it could be a bit problematic. The devices of course are with the kids and they are not necessarily nearby. Additionally, turning off the feature also diables a lot of convienience and sometimes necessary stuff (like app updates).
Really, I just need to know what apps are doing the billing. Then I just tell the kids to stop using them. I know that will work, and it won't disable or hinder their ability to use other features.
There is a bit more to this story. I want to know which apps are doing the billing because they are making a substantial amount of money ($1000 since February just from me) so they look like an opportune investment possibility.
My guess is that Apple makes enought commission from the In App purchases to make it worth their while to keep the infomation hard, or impossible, to find.
Thank you for your fine suggestions.
