Over at Atari I would usually post these in whatever subforum it related most to, but here I think I'll get a thread going on it. Think I've seen enough side remarks from other deal hunters that I don't have to worry about talking to myself...
Instead of posting "watch these sites" I'm going to keep it to actual deals for now.
To start us off:
Halo 3: Legendary Edition Xbox 360 Game
$29.99 + $4.99 shipping.
Less than half what Amazon is asking, and only a few dollars more than what Walmart wants for just the game.
