Yes we have heard/seen the book.  I have a copy which I bought from them 
also;  I think it's a rather comprehensive book for growers of the major 
species of CP.  However,  there have been bad reviews about P&P's.  They 
have been known to send specimens in less than good health and some have 
previously indicated that they might get their supplies from the wild and 
grow practically nothing in their greenhouses.  The former I myself can 
attest;  the latter is only from what I've seen on this group.  If you 
really want to see what people think about this business,  check the 
archives.
