I bought a Destiny 2 Cookbook, and as I was going through it, I noticed a card that said I can redeem in game items by entering the code on the back. There was a spot to scratch off for a code, so when I scratched it off, I found that it was blank and there was no code. I don't know if there was a deadline or not to redeem the code, and they just never took out the card, or if it was a misprinted card.
