We sometimes have overstocked or Scratch and Dent titles which we sell at a deep discount - usually 60% off retail. The books/CDs are new (not used) and complete in content, with minor damage (bent corners, scuffs on the covers or cases), or slightly imperfect printing, so we can't sell them as brand new. In some cases, the books have updated revisions for sale.
If you can accept slight physical imperfections, or work with older editions, you can maximize your education budget. Overstock/Scratch and Dent titles are sold "as is" and are not returnable.
If we have the title in Scratch and Dent, you will see that as a purchase option on the product page. If you don't see this option or if it is grayed out, there's no Scratch and Dent available at the moment. Availability changes, so check back from time to time.
