Hey guys,

I came across this Square Enix bundle. It says that I can REDEEM it for Windows (there is a key on the bottom of the picture). So like, I have the game on Steam, but if I donate to get this bundle, can I use the code to add 30 more days of gameplay, or is that just to redeem, as I am buying the game for the 1st time?
