Textbooks

I bought some for grade 12 from the bookshop today brand new and wow they are expensive but a lot of them are diff books than needed last year so hard to buy from ppl second hand.

umm i tried ebay its great for second hand textbooks

got some of mine last year from better world books
http://www.betterworld.com they are really cheap and only cost around $4 per book delivery from the US
some are secondhand some are new the ones i got last year were in great condition one was the past years text but still had all the same info and questions they were just numbered differently the new books question 35 would be the old ones 33 and the 36 would be 34 etc.
its wirth a look however they do take a while to arrive so i suggest you order ASAP mine too about a month to arrive

i also got some of http://www.thenile.com.au they are slightly cheaper than the bookroom and have free delivery

Sorry i dont know of any stores in sydney because i am a melbourne girl but i have heard of many different sites and some of my friends even go on ebay, they cause u can pick up some really cheep books there, anyways best of luck and happy studying
