While looking through a local CompUSA in Orange, CT. I noticed that they had put out a bin of games that had a sign next to them saying they were $4.88. The cashier had to manually put the price into the register, so it probably isn't going to be nationwide. Some of the games that were in the bin were:

Phantasy Star Online: Versions 1&2(xbox)
Drake of the 99 Dragons
Harry Potter and the Chamber of secrets(xbox)
NBA Inside Drive 2002
NFL 2k3(xbox)
Defender(Xbox)
Roadkill(Xbox)
Freestyle MetalX(Xbox)

Also, while I was in another CompUSA in West Nyack, in the Palisades mall I noticed another bin of clearance games. These were 2 for $30 though. Some I can remember were:

Tiger Woods 2003(xbox)
Lost Kingdoms(gamecube)
Myst 3: Exile(Xbox)
THUG(Gamecube)
Dragons Lair 3D(Xbox)

You might want to check your local CompUSA's to see if they also have the clearance sales going on.

I may have to swing by the one in S. Austin and check it out.
