I checked my local Target at least twice looking for it on clearance but didn't find. I'd been waiting and waiting for the game drop to at least $29.99 considering its a remake of an upgrade of game that visually still hold its ground even today...but it never did (at least I could never find it for that price). And my doubts of it ever really officially happen grow ever larger (in terms of new copies). As others have said, this game looks like it'll be the type that'll see the vast majority of its sealed copies fade away before it ever gets really cheap. So I recently broke down and bought a sealed copy for about $38.00.
I must say though, even though you can probably just settle for Black if you don't care to play as Rachel, this is the ultimate version of one of the best and one of my favorite action games ever and for its substance, its well worth $40.00 if you don't already own an Xbox version.
