Buy Borderlands for Cheap, Get the Expansions for Free
If you haven't gotten Borderlands yet, or any of its DLC, Amazon is having a great sale on the game with both Mad Moxxi's Underdome Riot and The Zombie Island of Dr. Ned included for free. You can get the game for $37 on the 360 or $27 on the PC and both pieces of content on a separate disc are free. Normally those content packs are $10 a piece! For whatever reason the PS3 version of the game is not included with the sale.
