One of the most shocking things a new college student experiences is shopping for textbooks.  One minute you’re innocently strolling the aisles of your campus bookstore gathering books.  The next you find yourself madly gasping for oxygen when you see the total on the checkout register.

Welcome to the scary world of sky-high college textbook prices.

According to a 2007-2008 report from The College Board, the average four-year college student spends about $1,000 a year on books and supplies.  Making matters worse, many students pay with a credit card and then let the high interest accrue.

Even more frightening, increasing numbers of textbooks are costing more than $100.  One widely used economics textbook from my college years now sells for a whopping list price of $176—teaching you about supply and demand in a hurry.

Fortunately, options exist.  Even just one of the following eight strategies can slash your annual textbook bill by 50 percent to 75 percent (or even more).

1.  Be first on campus:  Although buying new textbooks at your campus bookstore is frequently your most expensive option, limited numbers of used books may be available if you get there first.  Used books typically sell for around 75 percent of the new book price.

2.  Price it online:  In addition to checking online booksellers like www.amazon.com, www.bn.com and www.half.com, you may find even better deals by using comparison-shopping sites that prominently feature textbooks.  Some of the best include www.bookfinder.com, www.studentshopper.com and www.bestbookbuys.com — all of which offer the latest prices from a wide selection of online retailers.

And remember, you will need to allow at least a week, maybe more, for order processing and shipping.

3.  Consider alternative formats:  Selecting an electronic version of a textbook instead of a printed version can save about 50 percent.  And at websites like www.coursesmart.com, a site created by six major textbook publishers, you can electronically highlight the on-screen text, add your own typed notes and perform a keyword search on the entire book.  For those who believe “free” is a very good price, you also can download many classic works of literature for no charge at www.gutenberg.org.

4.  Consider a prior or international edition:  According to a study by the Government Accountability Office, publishers are releasing new editions of textbooks more frequently, even though not every revision results in substantial content changes.  If a new version of a textbook has only minor changes, you might not need to pay top dollar for the latest edition when the prior can be had for much, much less.  Likewise, many publishers sell the same textbook overseas for substantially reduced prices (perhaps with a soft cover instead of a hard cover).  You can find these foreign editions by using the same comparison-shopping websites listed in Strategy No. 2.

5.  Prioritize the reading:  Because not all textbooks have equal importance in a given class, talk to past students to determine which books are critical.  For those that are essential, invest in the current printed edition.  For others that may be referenced only minimally, you instead might opt for an electronic version or older edition.  And if your class syllabus indicates you will be assigned only a couple of chapters from a book, either check it out at the school library or locate it on a website like www.ichapters.com, a site where you can buy electronic versions of specific chapters for a few dollars each.

6.  Rent a book:  Much like online movie rental sites, www.chegg.com and www.bookrenter.com offer students the option of renting a printed textbook.  For instance, that $176 economics textbook I mentioned can be rented on such sites for between $66 and $95 depending on the length of rental.  Just be sure to read the fine print because late fees and damaged book fees are hefty.

7.  Swap a book:  The concept is simple:  Gather a group of students in your academic major and agree on a fair way to share the books you will all collectively need.  Because different students will be taking common courses during different academic terms, swapping books could save you a bundle.

Alternately, websites such as www.swapsimple.com and www.bookmooch.com make it easy to swap books with others online.  Because some colleges have created their own online book exchange websites, be sure to ask around about what’s available on your campus.

8.  Maximize the resale value:  Because your campus bookstore will probably pay only a fraction of the original purchase price for a used book (typically up to 50 percent of the original price), you often can recoup more cash by reselling the book to another student or else posting it for sale online.

If, however, you are someone who learns better by marking up your textbook heavily, don’t sacrifice your reading comprehension just to keep the book in pristine condition for resale.  Although it’s always nice to earn back some much-needed cash, it ultimately earns you more in the long run to make sure you excel in your studies.
