Textbooks
Amazon isn’t the only online retailer with good deals on new and used textbooks. At the end of the school year especially, the Craigslist books & magazine section is usually overflowing with $200 textbooks selling for just $20. (The schoolbooks on Craigslist are so famously cheap, in fact, that some people scour the site for the books only to sell them on Amazon for a hefty profit.)
