For students interested in taking my Intro. to Linguistics class this coming semester I have a couple of suggestion about how to get the main text cheaper.
I found it for 34.00$US on the following website.
That is the cheapest I have seen the new book.
Alternatively, there are several cheap, used copies available from Amazon. com.

Hope this helps.
