Have a look at ebay.co.uk (online auction) - There is a whole catagory on "Pilots gear" - The Pratt books and Thom books are both currently listed together with protractors, whizz wheels, etc., not to mention headsets, goggles (!), aviation GPS's and other paraphanalia.
I bought most of my stuff this way: CRP-1 less than 20 quid, Thom books at less than a tenner each (make sure that they are recent editions that cover the JAR course and also make reference to the most recent Air Nav Order (2000) in respect of the Air Law exam).
I suppose in total I've saved less than £100, but that pays for another hour of training.
