Even PS2 games don't really drop below $20 at the retail level. It may be clearanced at Circuit City for $17, but the $3 shouldn't be the deciding factor. It's a pretty fun game, not great though. Even if it comes up used at gamestop.com and you use the 25% off coupon, it's still going to be about the same price after shipping. If $15 is your mark for this game, I'd probably get it now anyway. If you were thinking $10, keep waiting for craigslist in a year.
