I was in a parenting forum online earlier today and a mom was shocked that her child had managed to spend $300 while playing a Marvel Superhero game on his Kindle. She contacted Amazon right away for a refund, and we all had a laugh with similar stories of our own kids.
Mine once spent over $245 feeding Tom the Cat and Gina the Giraffe on my iPad. I about had a heart attack! Apple was very good about refunding the money. My biggest complaint was that the app makers made it difficult to tell if you were spending game money or real money. Regardless, we learned to disable the allow in app purchases option on our devices that day.
So, tell us... have your kids made unauthorized purchases while playing online? What did you do?
