At the urging of my daughter, a middle school history teacher (she has gotten text books), I went on Amazon.com, put in the name of the book. If they have it, you get a list of both new and old. I recently got a quilting book (brand new) for 25% of the published price. Of course you pay shipping and handling but it still came to much less than the published price and even the 30% you get off at JoAnns (down from 40%). There were listings for much less; I just opted for a particular one. Will do it again.
