To redeem a code, login to your account at marvelheroes.com, click on the profile link once you've logged in, select the REDEEM KEY option in the panel on the right, and enter the code. Once the code has been accepted, the indicated item(s) will show up in your character inventory in game right away, though if you are playing, you may need to log out and log back in for that to happen.
Please let me know if any of the codes are not working and I will update the list.
