Redeeming preorder costumes


Just got my PS4 copy up and running after preordering from Best Buy a month ago. How do we redeem the costume DLC? Thanks!

Edit: Figured it out, haha. In my case I got an email from Best Buy just now that contained the code, which I used in the PlayStation store. Leaving this here in case anyone else is confused. Please let me know if it’s better to just delete it–I can’t seem to figure out how.
