Hello! We are former homeschool parents who spent 18+ years purchasing used homeschool curriculum. We understand the importance of knowing what you are purchasing. So, we go through books page by page and test media, doing our best to represent curriculum as transparently as we can. This listing includes: Teaching Tape Tutoring Saxon 7/6 4th Ed FULL SET OF 15 DVDs — Original Binder case and sleeves in very good condition. — DVDs Tested and Working! — Surface scratches on some DVDs ***The great benefit of purchasing DVDs over digital versions with limited time to use is you now OWN something of value that can be stored and used again or sold.
