I typed in the code on the red bull site. Great, it hasn't been stolen yet! Cool. So then I get to the Bungie site and I have to choose which platform to apply it to. I use the same gamertag on XBL and PSN. So the dropdown just shows me the two gamertags without showing me which actual platform I'm choosing! I guess I could unlink my Xbox account, since I only play Destiny on PS4, but that's just poor website design.
