(Kind of?) stupid question coming here.

I made an account on this website and just purchased a copy of TW:Warhammer since it was slightly cheaper here than on steam, but I'm not getting any gamekey in my mail and I can't find it on my account either.

Do you usually have to wait to recieve your gamekeys from here or have I just missed something? Otherwise I might as well just refund the game and buy it through steam normally.
