No, you can’t pirate it to get it cheaper, but what you can do is head over to Amazon.com to make your purchase. Amazon is already selling Left 4 Dead 2 at $54.99, but on top of saving that $5, when you order from amazon, they will give you a $10 game credit back. That technically makes the price $44.99 for this game.
Sounds like a great deal to me, that’s $15 you’ll save overall and $15 extra someone will spend buying it somewhere else.

Essentially, it’ll only be costing you $37.50 each.
Very, very tempting. I’m not usual big on buying new games, a little too expensive for my tastes. But for $45, I just might….
i can dig it! zombies are hip right now!
Well if you buy it on steam its only 44.99 but you don’t get a gift card
Amazon has been stepping up lately when it comes to deals on games. I want more of this.
Hmmm, I am still debating if I want this on PC or 360, and this deal makes it even tougher. Damn you Amazon, DAMN YOU!
wow
that deal is for any system?
Nope, this is 360 only it looks like
Awesome! Now I’m definitely buying it on Amazon!
