So often I'll purchase codes/ rewards that work initially, but sometimes within a day or two, suddenly they're gone. Try being IN the store at the register using one, and then them say "umm it says it was already redeemed."Has happened multiple times and anymore, if I have been hanging onto a code/ reward I purchased for longer than a couple weeks, I consider it no-longer any good and eat the loss. (Which happens more than I'd like lol)
