While the majority of the materials on their site are not free, they do have a couple of things you can try before you buy. There are two free sections: Power Point and Quizzes. I haven't bought any of their items, so I can't comment on the material they offer for a fee. However, you can try the free stuff and ask your school to purchase the rest.
Got an idea for a cool link?
Email me with your cool link, name, and website (if you have one) and I'll post it ASAP.dpw
