As every student knows, the cost of some textbooks will make your budget flinch in horror! Buying used school books, in certain cases, can save you a load of money. It all depends on the topic and what title your instructor is using for your class. If you can find that book, used, but in good condition, you can save about 50% at the campus book store. In other cases, you can find some excellent reference material online, at bargain prices, which, while not on your list of required reading, may prove quite valuable in terms of helping you to excel in your major and building your permanent library. For example, if your major is journalism, a used school book on the history of journalism will definitely enhance your knowledge.
