Don't feel too bad about it if you were given a code and don't know if it was taken. I was given mine early on in the promotion so I hope they weren't stolen. But if they were, I'm sorry to whoever it took it from. I wish Red Bull put more thought into their codes but there's nothing that can really be done now. Stealing codes is wrong, but I just wanted to post this for people that aren't at fault who were given their codes. If your codes were stolen you can send a picture of the code to Red Bull and get a working one. Here is the link to contact Red Bull for new codes if yours don't work :-) http//:energydrink-us.redbull.com/red-bull-quest
