Every year students flock to the college bookstore to purchase the different textbooks that they need for their classes. Little do these students realize that, in doing so, they are throwing good money away. It may sound unbelievable but textbooks, in some cases, actually cost as much as, if not more, than college fees.

Many people think that college bookstore are the most convenient source for textbooks. Titles are usually in-stock and students may purchase new textbooks or  choose to buy second-hand books and save money . But the money saved by purchasing second-hand textbooks from college bookstores is small compared to the amount they could save by shopping online.

More and more online booksellers have begun selling textbooks at heavily discounted prices. Online second-hand bookstores are another source for college books as they stock a large number of textbooks, which means sizable savings for students. Students should avoid purchasing their textbooks at the first store that they browse online since there are so many ‘virtual’ booksellers on the Net. Price isn't the only factor to consider when making an online purchase. Students should also consider shipping costs and delivery time when making their decision.

Online auctions(拍卖) are another option for students seeking a bargain. This option, however, has its pros and cons. A plus is that students can get incredibly cheap books. One problem is that while online bookstores have a system in place that ensure  you receive your order within a reasonable amount of time, with an auction purchase, however, you  must depend on the auction seller's timetable.

One way that students can really save is by getting books for free. Project Gutenberg is one resource that English majors will find invaluable. Here students can legally download a huge collection of classic novels. In the past students needing help with their studies would often have to spend a lot of money buying expensive study guides. Today that is no longer the case. Cash-strapped students can now visit the website SparkNotes for free downloadable study guides as well as classics.
