"Book Prices" are estimated guides only and it is impossible to predict what someone will bid for a particular chip on "dumpbay" where lots of folks happily accept anything they can get for their no longer wanted "stuff".

Having said that; I'll admit that Ebay is sometimes a very good place to shop for a bargain. Some folks buy cheap on ebay to sell at "book price" later on. You know how that works Mudbone ... right??
