Please use the internet-based book store for any bargain textbooks, now I have some which I used most during my times of studies. 7 x$ a% D4 h& e5 N& d: K6 r' r& R _1 b" H$ P, q; r
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. ) ; H( D5 ^' Z& z t, D: K , o; `: Q7 ^2 K- nThe 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 * z8 |9 S9 k- v8 i! @" h; J' `9 r1 \# g
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' ~4 i1 ^" k' U* T4 b! |3 q

Therefore borrowing from the university library as fast as you can would be even better, yet absolutely cheaper. 7 x5 Z. `7 D6 K7 s0 Y9 i. \; Y, O- J$ k% M% ^4 z P
So you don't actually need to walk that far for seeking Bargain shops, everything can be done online. : J# p0 W {+ \* G, r" p6 ^: g i2 S" H/ V4 W
