Only redeemable on Steam using the activate key function (aka if you have it you won't get an extra copy nor anything in your inventory, so it can only be usable on an account without the game), instant digital delivery. Very high discount on games, almost all of them 80%+ off retail in USD.
Game List, subject to actual availability on the store of course:
