Textbook Availability

[mr tin]

I am finishing up my Masters in ESL and am planning to go to China in a year to teach English long term. I have several text books already, which I've obtained from my courses and several more I would like to purchase. I am wondering how easy it is to find and order good quality English text books in China. Are English textbooks hard to come by? Are they easy to come by, but rather expensive? I am interested in some more specific topics, such as discourse analysis and pragmatics and am not sure how difficult they would be to find. It is not an issue to order them now, but I am trying to avoid paying unnecessary shipping costs. I realize that the school would likely have their own textbooks. Mainly, the books I speak of are for personal reference.:)
