Howstuffworks has some great money-saving tips for anyone starting or returning to college or university. Some of them, like the tip below, apply to most high schools as well.
Buy Textbooks From Used Bookstores
New textbooks from university bookstores can be very expensive. Brand new editions of chemistry books, for instance, can cost as much as $300, and that’s not including any lab material. However, you can cut costs on reading materials and not starve. Look around for used bookstores. Most college campuses should have several — the prices are heavily discounted, and book conditions are usually good. If you have enough time before classes start, check out the Internet for your books. Even with shipping charges, prices can turn out to be cheaper from online bookstores.
You can definitely get great prices online from Half.com or Amazon, but be weary of buying books that you might not need. Personally I had 4 extra books last year that were marked as “needed” for my courses, even though we didn’t use them. In this case, you might save more money by purchasing books on an as-need basis from a local used bookstore.
