Yes, that's part of the fun at a chip show, seeing how far apart the price is on the same chip with the different dealers. I used to occasionally mention to a dealer who had a chip way overpriced if there had been a "find" of the chip and the market price had gone down but often the dealer's attitude would be, well maybe I'll find a newbie that doesn't know and I can unload it on them, so I've pretty well given up on pointing it out anymore.
