Used iTunes gift Cards
I purchased this afternoon 2 iTunes gift cards to send to someone for their birthday via email. I took pictures with my iPhone with receipts and back for pin number and sent to my laptop to send via e-mail. When they tried to use them, it told them they were used. I checked to see if the amount was mistakenly added to my id and I don't show a balance. Please advise.
