just got back from K-mart they discounted a bunch of gaming stuff, 360 Plants v. Zombies $6 Viva pinata $2 Topspin tennis $2 Bioshock was $6 I passed since I already have it PS3 Brothers in Arms highway to hell $2.00 Rainbow six vegas $2.00 Haze $2.00 Large graffix stick anywhere gaming stickers $1.00, I got a few of the Link and Mario ones. I remember seeing a bunch of psp stuff as well. memory cords and link cables. Not sure if this is everywhere or just my store, its worth checking out.
And that's why I hate my country: we'll never see that kind of prices for video games... not even close! Cheapest used games like the ones you mention are probably around USD 15.
