So I’m attending University of Washington starting this Fall. Among many other problems, one is finding textbooks for courses at a reasonable price. Books for some courses may set you back by as high as $250 (per book). A little too high, isn’t it? On an average, textbooks for undergraduate study of four years can cost as much as $5000.

Unlike other personal expenditures, there’s no real way to cut expenses on books. If it’s needed, you have to get it. As with everything else, Internet can be real rescue to find college books for extremely low prices.

Below are 8 websites to find, buy, sell, trade or rent your textbook. Let me know in the comments which one you use.
