Price drops & deals: SingStar for $20, Far Cry for $40, more

Looks like a lot of games have dropped in price. Bad sales? Bad economy? Or just good deals? Prince of Persia for $40 at Gamestop Guitar Hero: World Tour for $50 at Gamestop Midnight Club: LA for $40 at Gamestop Far Cry 2 for $40 at Gamestop Grand Theft Auto IV for $40 at Gamestop Tom Clancy's End War for $40 at Gamestop SingStar for $20 at Newegg (this is the game only and doesn't include mics) It looks like most of these drops will be permanent. Who knows? Maybe these prices will continue to plummet. [Via Aeropause]
