Please use the internet-based book store for any bargain textbooks, now I have some which I used most during my times of studies. / n- v6 T1 u3 w: @/ ? A- |9 J2 P1 l* _2 p
One is as-you-mentioned "Second Hand Book Store", please use the link: http://www.abebooks.co.uk (This one really rocks, and I believe it should meets most of your demands. ) 8 k! x) m% c, r R, \7 g8 ]: ^2 a2 N8 F$ ?6 \3 J" ^
The other one - Amazon, however. It's not always cheaper than Abebooks, but you will find an even wider range of the book selections: http://www.amazon.co.uk , q/ x' A# d2 D U' U4 N$ D% Y( v( c+ C# L/ I. E9 E
The third one, which I used not that often, as this one actually has the real book stores all around the UK, named Waterstone's: http://www.waterstones.com - Q9 R O/ G2 J. Z. N- a) M1 t, n3 N8 c9 T: T7 a+ r: I* y8 Z
Besides, for a postgraduate student, you may not have to purchase every book listed on your reading list, it's just simply because you need to read at least 4 or 5 books for a single course per average. Therefore borrowing from the university library as fast as you can would be even better, yet absolutely cheaper. 5 u& `5 W0 M, q. s$ y
