Hey, just in case because it happens quite often: maybe you were trying to gift The Culling Of The Cows, but you couldn't find it on the list?!

That's because this game was given out for free. Once games were given for free they cannot be given away anymore, it's not allowed to prevent abuse of the leveling system. It makes no sense to offer the soundtrack instead, as only people who already have the game will be able to enter this. They will expect you to gift them the soundtrack. You are going to get a "Not received" feedback.

Also per rules this is called a "Misleading giveaway", as you are not gifting what the label says. This will result in a ban from the site and the giveaway will be deleted when support finds out. If I may give a little advice: better delete it yourself to spare being locked out from this site (if only temporary).
Please read the faq and guidelines. Here you can look at punishments for several things that can go wrong.

hi, your key is The Culling Of The Cows. Not Soundtrack DLC.
I can't receive it.
