Get one of four games free when you buy a 320GB PS3 from Amazon

For a limited time, Amazon is offering a great deal on PlayStation 3 320GB consoles. Purchase the system and add one of four select games to your cart free of charge: MLB 12: The Show, Uncharted 3: Drake's Deception, Twisted Metal, or Gran Turismo 5 XL Edition.

All of these games have largely positive rankings and released either this year or in late 2011, in the case of Uncharted 3. That's more than a fair deal on games that would otherwise fall in the $40-60 range, and it contains some of the PS3's best.

The 320GB PlayStation 3 model costs $300. The alternate, 160GB model sells for $250, which isn't much difference in price to begin with.
