New Courses

Does anyone know if the new supplemntary Chess Mentor courses are avalable for purchase on a CD? There is a course by Nigel Davies and  another one by Wolff advertized on Chess.com but it doesn't allow you to purchase them. The Chess Mentor Site and the largest Chess Store doesn't have them. I did see a course by Wolski Essential Checkmates for sale on the largest chess store site and I don't see this one on my original Chess Mentor Deluxe version. Did this come out as supplementary course after the Deluxe version was out?

That is correct. There are numerous courses which are unique to the Chess Mentor web edition at www.chess.com/chessmentor

Each month new courses are introduced to the Chess Mentor Web version.
