We currently have two used copies in stock at just $40 (sells new for $60), but the pricing is partly because each has issues with condition. One has a one inch wide indentation in the top of the back cover, where it received a blow (likely in falling off a bookshelf), the other has pink staining at the top edges of the pages, due to some kind of spillage (lemonade?). Internally, both copies are fine. Please specify preference when ordering.
