I think my granddaughter bought a $3.99 app after I put the password in for a free app. How can I find out what she purchased? Can I get credit for it? I just got an email from my credit card confirming the purchase.

The password is good for 15 minutes to make purchases. You should receive a receipt in 24 to 48 hours for the purchases. There is a link to Report an issue. You could use that to start a conversation with iTunes Support about a refund.

Apple considers all sales final. But has been known to offer a one time refund. So the question is, do you want to use your one time refund on this purchase or one more expensive in the future?
