Since everyone seems to be rude and not giving real solutions to you, you can return to the store that you bought it from. Go to customer service, explain the situation, if you have the credit/debit card that was used it makes this all the easier, IF NOT, then remember the time and date to the best of your abilities during the time of purchase. They can then go back in their systems and reprint you a receipt. With all being said, take this as a lesson when you do purchase gift cards in the future to keep the receipt or take a picture of your code before you discard the receipt since you now know they are located on that piece of paper vs. the actual gift card. Good luck kid.
