Now, the titles with ?? as the price are no longer available by themselves for whatever reason, however they are part of franchise bundles. With this in mind, it's a reasonable assumption that if you remove the other game(s) that are part of these bundles, you'll end up with the price of a particular game itself. With that in mind:
Tom Clancy's Splinter Cell Conviction - Deniable Ops: Insurgency $15
Far Cry 2 $50
Lastly, neither the original Assassin's Creed nor the sequel are available separately, so the only reasonable course of action is to simply halve the price of the bundle:
Assassins Creed® II $54.975
Assassin's Creed® - Director's Cut Edition $54.975
Assuming I didn't mistype any of the prices, I managed to grab $2106.79 worth of Ubisoft games and DLC for the tiny price of $0.00.
Thanks, Ubi!
