They are currently running a buy one get one free offer for all the used games $14.99 or less.  I got me GTA IV and Virtua Fighter 5 for the360 together for the cool price of $15.  It was slim pickings at the stores I went to, and Forza 2, which is what I also wanted was not to be found, but overall I am glad about the clearance sale there.

Woah! They had GTA4 for $15? Ill just have to pick a copy up at that price! WOW

GTA 4 for $15, and a second game that's of lesser or equal value for free.  You may have to drive around a few stores to find one that actually has a copy though.  I went to three and one had two copies GTA 4 for 360 but none for PS3, the other had a couple for PS3 but none for 360.  The third store didn't have any.  I chose the 360 version because of the upcoming DLC.
