The whole list is in the link. Some kind of halloween sale and I'm unsure when it expires.
Resident Evil 5 looks pretty good though since the gold edition for the PC is probably not going to happen.
It's a great co op game for those who haven't tried it.
You download the game(s) once you buy it.
For those who want physical box copies, last time I was at EBGames they had the budget version of Resident Evil 5 for $15 also.
