"Left 4 Dead is getting close to its November 18 launch, and Valve is now happy to accept your money: the PC edition is now available for pre-purchase on Steam with a 10% discount before the game's release, making for a price of $44.99.

For those resisting the PC incarnation of the run-away-from-zombies shooter, the Xbox 360 version will hit retail on the same day. The 10% discount also applies to pre-purchase customers at retail outlets, according to Valve's press release. "
