Target brick and mortar stores have a number of good clearance prices on decent games. I just picked up PC versions of Borderlands, Red Faction-Guerilla and the Bioshock/Oblivion combo disk for $10 each. I also snagged a copy of Bayonetta for PS3 for $15. I went to a different Target and they had Borderlands for $18 so it will vary by store; your mileage may vary. BTW, they also had the new PC version of Wolfenstein for $18, but I thought that was a bit steep for a clearance game.
