Check out some local Blockbuster/GameRush lately... They been clearing out allot of titles out lately...
-Couple weeks ago, I bought SC4:LE for PS3 for 25/30$ (Which has a sealed copy of SC4 , which I could sell or return to Walmart,lol since I have it already). Also the new SoCom for 30$ (Really I wanted the new HG Head Set that came with it, which is an Awesome Head Set and Way Way Cleaner sounding then the older ones that came with Warhawk, So Basically I saved 20$ off the headset by itself and got a crappy game with it). They also had some other great deals, Assassins Cread for 10$ and many other titles about 50% or more off!!!
-Also with the PS3, You can download it up to 5 times from the account that was original used, Then any account on the system you download it can use it... Basicially if you know someone with the code, just log into their account on your system and redownload it...
-With XBox, not sure if that is the same case. Think its the usually only that account can use it even if you are on the same system.
