It's a glitch in the SteamGifts site. For some reason, SG is taking the pricing data from the Daedalic gigantic bundle on Steam, instead of the correct individual pricing. Oh well. Perhaps the overall entries will be lower this way.

I believe its base price was actually $40. Just some problems with SG price recognition. Nothing terribly important.
Perhaps it'll keep people who don't really want to play the game from entering and capitalizing on the generosity of the gvier.
