Do iTunes gift cards expire

At least some iTunes gift cards has expiration dates. If you have a physical or electronical gift card bought from Apple or an Apple partner, it should be marked with expiration date if applicable. However, once the gift card has been redeemed in iTunes, there is also a question if the actual credits also have an expiration date. If so, you will see the credit expiration date on the confirmation you get after redeeming your code.
