I entered the code in the box and it said to activate your 48 hour trial reset your console. I did and when I came back it was still sliver and when I tried to enter the code again it said the code was invalid. It took my card and gave me nothing back. if it does this to trial cards, I'm scared to put a $50 one in there. You go under accounts to enter it but it will probably take your card and give you shit like it did to me.
