sometimes it helps if you are a regular and you are nice and polite, not arogant and obnoxious when you try to negotiate there, they get tons and tons of creepy ebay resellers in any of those stores dayly and they generally don't care to deal with them much (as they can be pretty fucking obnoxious over the difference of a dollar or two) but once they realize you actualy enjoy the games instead of just flipping them, you'llfind they'll be more open to negotiations. and if you are one of those anoying flippers well....TOO BAD! ;-)
