Teaching Company: High School Math

I've been waiting for what seems like forever for The Teaching Company to put their high school math courses on sale. Finally, the day has come. And just in time for the school year.

If you're not familiar with The Teaching Company, they provide videos/DVD's of college and high school courses by the best of the best professors. All of their courses go on sale at least once a year, often for 75% off.

If you see any courses that you absolutely must have but are not on sale, EBay is a good source. I've seen them scooped up there for very reasonable prices. Cheap in fact. And, some public libraries carry them as well.
