On the off chance you're still holding on to that holiday cash you got from Grandma (she loves you very much), you'll definitely want to check out the sale currently going on at Amazon. It's pretty simple: Buy three games and you'll get the cheapest one free. Over 380 games are included in the sale, representing every major console. Highlights include Vanquish, Need for Speed: Hot Pursuit, Dead Rising 2, Gran Turismo 5, Ghost Trick and more.
As a willpower exercise, head over to Amazon and try not to press that "add to cart" button.
