not much, don't waste $$ la. if you really want, either buy 2nd hand (one of my friend-bk mom wants to sell it>>99% new) or go to palmchristy's website to download and print it (better red ink) by yourself la I suggest your friend use the $$ to buy some other books, like ORT.
BTW, Glenn Doman has published a set of cd-rom (I, personally, think is much worth to buy)
