I just picked up a used copy of Baten Kaitos for $15 at Game Trader in Cuyahoga Falls, OH. As far as I can tell, Game Trader is not part of any sort of retail chain, and I picked up the only copy they had. Consequently, this information probably isn't useful to any of you. I figured I'd pass it along anyway, so you feel like your overpaying when you pick up your $30 dollar copy on eBay.
