I just listed my Great Courses Economics, 3rd Edition, set on ebay in case anyone is interested. The beginning bid is only $10. We used the videos along with an econ text book "Foundations of Economics: A Christian View," by Shawn Ritenour. I recommend it highly. http://www.ebay.com/itm/282667931835?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649
