Gee whiz,
Lovely interest in Jack Gwaltney's book. Take it from me, he will be absolutely thrilled.
By the telephone orders and the orders so far on this forum I will definitely need more books.
I have no idea of the costs, as I only ordered them yesterday. Plus I have asked Jack to send them via US post, on the quickest service available.
I also want to take this opportunity to state that this particular book speaks more on theory than "how to train". That being said it is one of my absolute favourites.
