Left 4 Dead gets $5 off with pre-order

We're not exactly sure if we've ever seen a deal like this before, but those who pre-order Left 4 Dead on PC and Xbox 360 will get $5 taken right off the top. This makes the apocalyptic, action survival game $45 and $55 for PC and Xbox 360, respectively. The special deal applies to both retail and Valve's Steam service.

We're not positive if the price of the game will go up after its Nov. 18 release, but we certainly like this pre-order discount idea if it sticks.
