The people who take advantage of these options can save hundreds of dollars over the course of their education. Amazon.com is not the only or always the cheapest place to buy.

• 1) Before buying a textbook online, be sure that you've found the correct book and edition specified by your professor.
• 2) One thing to look out for is international editions. They are usually cheaper and have different, soft covers. They may or may not have significant differences beyond that, such as missing some illustrations. Know what you are buying.
• 3) A major issue encountered with buying books online is shipping. Remember to look at shipping costs. Many online book retailers (not just Amazon) offer free shipping for a purchases above a certain price. Also, try to order the books as soon as possible so that they arrive in time.

These books include everything from the work of Mark Twain and Sigmund Freud to dancing and etiquette instruction manuals from the late 19th century. You can find these books online at one of many public domain search engines and online libraries.

• Whether you are buying from a trusted retailer like Amazon or a small independent publisher using PayPal to process transactions, some internet buying safety tips apply across the board when it comes to protecting you from identity theft.

1. Use the most recent version of your Internet browser. It will usually update automatically, but you can check for updates under the Help menu.
2. Check to see what the web site's security policies are. They should be easy to find. If they're not, that's a red flag about the retailer's trustworthiness!
3. Look for a little lock symbol at the bottom of your browser when you are submitting your information.
4. The letters "https" should appear at the beginning of the URL if you are on a page where you will submit your personal and credit card information.
5. Make sure to keep the receipt for what you purchased. You should be able to print one out at the end of your transaction.
6. Check your credit card statement for any errors.
7. Don't ever give out your credit card information by instant messaging service or email.
8. Notify your credit card company immediately if anything fishy happens.

• Whether you're buying used books from an independent seller on Amazon or a new book from an author's personal website, take some time to investigate the seller before making your purchase.

1. If you are buying used books from an independent seller on major sites like Amazon or Alibris, check the seller's history, customer feedback rating and return policy.
2. Check to see if a smaller retailer's site is secure. Does it have emblems that say "Hacker Safe", "Verisign Secure" or "BBB Reliability Program"? Then it has been approved by a trustworthy organization. Retailers without these emblems often are not trustworthy.
3. A trustworthy retailer will have a 1-800 or 1-888 number for you to call in order to reach their customer service. If they don't provide any phone number, that is cause for suspicion; if they don't provide any contact information at all, they are certainly not trustworthy.
4. Look for a good "About Us" section that includes information on the company's policies, features, and even a brief history. If they're not giving you that information, you probably don't want to give them your money.
5. What is the site's return policy? Reputable sellers stand by their products, and offer customers the opportunity to return items that aren't up to par. If the return policy is restrictive or non-existent, caveat emptor!
