I went to the SUPER ghetto WalMart in LA, the one way down Crenshaw in the Crenshaw Plaza...they had a bunch of Grim Grimoire and Shining Force EXA in the case, but no indication of a mark down and I didn't price check them since I have them. Also I believe they had Rogue Galaxy...if not the Sears in that mall had a ton of them in the clearance bin so hopefully they are $20 at most.
Unfortunately the Sears didn't have Persona 3 which the online site claims they do have available for store pick up.
No clearance game bins at WalMart but a bunch of bins stuffed with DVDs, from the look of them mostly older crap. The store was a complete warzone.
Edit: Apparently Sears has Rogue Galaxy clearanced for like $10. If anyone is interested in a swap, I would be willing to go and get any of the games but only for trade for some of the Circuit City clearance games, mainly Mario and Luigi Partners in Time DS and Metal Slug Anthology Wii. Check my post in the CC clearance games thread on game trading for what else I'm looking for.
