Hello LED. You'll need to go to your [url=https://www.bungie.net/en/Profile/Rewards]Bungie Rewards[/url] page and find the reward you want to buy. Click the "Email Discount Code" button, then check your email for the discount code. There seems to be an issue with the Rewards page not working correctly, but the email should still be sent to you. Click the "You have a Bungie Reward waiting for you!" email and click the blue "Claim Code" button in the email and it should direct you to your code. From there, go to the [url=http://bungiestore.com/]Bungie Store[/url] and find the item you have the code for, add it to your cart, and during checkout is where you can use your code.
