The Barbie app has features you have to say yes to install as you play. A lot of games have this so you have to be aware before you download the app. It's posted in all the reviews of the apps that have this. All the child has to do is touch the yes button for the charge. Most don't realize it's a charge but know if they touch yes they get new features on the app. ITunes refunded one app for me that I bought but it wouldn't work on my Itouch even though it said it would not work, I didn't read all the requirements. ITunes said one refund this time only.
