Textbook info should be scraped from the Campus Bookstore site

I'm seeing the site use something like this:


    Request URL: http://www.campusbookstore.com/textbooks/searchengine/Default.aspx
    Request Method: POST
    Form arguments:
    ctl00$ContentBody$DepartmentList$9: on //9 is the index of BIOL
    ctl00$ContentBody$CourseList$0: on //0 is the index of BIOL103

Possibly optional:

    ctl00$ScriptManager1: ctl00$ScriptManager1|ctl00$ContentBody$SearchButton
    _ASYNCPOST: true
    ctl00$ContentBody$SearchButton: Search For Textbooks >>

But a quick try with `requests` wasn't successful.
