There was an Ultimate Electronics that closed down near me last month and I managed to snag Fable III Collector's Edition for $20, Assassin's Creed Brotherhood Limited Edition for $30 and then on one trip I got Splatterhouse, Blood Stone and Just Cause 2 all for $30.
I went to Target yesterday and picked up Army of Two:The 40th Day for $4.98.
I got the Aliens Vs. Predator Hunter Edition on Amazon for $24 new a few weeks ago.
I also got Dark Sector and Jericho for $5 a piece new on Amazon too.
Where there's a deal, you'll see me.
