$49.98, just over $30 less than the retail price of $79.99. Lest you've forgotten, the collector's edition comes with a Vault Boy bobblehead, a 100 page art book, a making-of DVD and a sweet metal lunchbox (It also includes the game, which is important). If that sounds just a bit too paltry for your expensive taste, Amazon is also offering its exclusive Survival Edition for $109.98, a $20.01 savings over the regular price. The Survival Edition includes all the extras of the collector's edition, with the addition of a replica Pip-Boy digital clock.
Like we said, if you've been waiting to get Fallout 3, nabbing the collector's edition for less than the standard edition is a pretty sweet deal.
