Books

I went book shopping yesterday - not for "fun" books, but for next semester's books. I am taking four classes - 1)comparative literature; 2)elements of health; 3)fundamentals of music; and 4)interpersonal communication. The book for health was used at $45; the CD for music was $92.75; the communication book was $78.25. I didn't purchase the books for literature from the bookstore because there isn't a text but several novels that I intend to purchase, used, on Amazon or some other on-line service. I can get all but one (still searching) for less than $3.00/each. Wasn't there discussion some time ago about why text books are so very expensive???
