I contacted the store where I had bought the games, and they reported that my purchase and many others was revoked. Apparently there was a mistake from the store site where the games were made available with the wrong prices on a promotion. I apologize for the inconvenience. I've had my games revoked as well. :(

I am trying to delete the giveaway because of the inconvenience. I got in touch with the SteamGifts site support and they said that the winner's permission is needed. So if you agree, could you please post a comment saying that you approve the deletion of the giveaway? And once again, sorry for the inconvenience.
