Any senior will tell you that you shouldn’t buy your textbooks at the bookstore. You probably pay enough tuition… there’s no need to buy $150 physics books. Instead, try any of these online bookstores: Half.com, postyourbook.com, amazon.com. These sites sell books at a mere fraction of what your school is asking. Used books are often better than new because the highlighting is done for you! To save even more, rent your books from the library or half.com.
