I, like many of you, have been trying to budget my app store spending on a budget. Personally I've been trying to keep my receipts at $10 or less. I found out that if you go into your account info and retype your security code for your credit card, it automatically resets your bill. That means if I already spent $10 and a new game came out that I wan to try, all I have to do is go into my account info and retype that number and I start from $0. It's completely cheating.
