5 hours ago I bought at CVS Itunes Gift card, code to be seen (may be photographed), and now I want to use, redeem display "This code has already been redeemed"
Welcome to iMore. Sorry to hear of your loss. It seems the card was redeemed by whomever stole it from you. Unfortunately there is not much you can do. Wish I had better news for you.
That stinks Depending on the actual circumstances (I'm not sure what code to be seen (may be photographed) means) you may be able to get some help from CVS and/or Apple if they can show when it was activated vs when it was redeemed. But as @firedept10 said, you're probably out of luck.
