Find out from your college which textbooks you will need for your upcoming courses. If at all possible, also get the International Standard Book Number (ISBN) for each course book from the school.
On the Internet, research availability and prices for the course books by visiting bigwords.com. You can compare prices at most stores on this site. Other sites that you can visit to check pricing are Half.com, eBay and Amazon.
Enter the ISBN, title or author for your first course book, then click "Go."
Choose your textbook from the resulting list. At Bigwords, click "Buy (Add to Bookbag)." Continue the same process for additional course books.
After you have added all required course books to your Bookbag, click "Start Price Comparison." The results will come up in three tabs. You can look at the best value overall, a single store purchase if available or all price comparisons.
Click "Buy These" to make your purchase. Bigwords will redirect you to the sites that you are purchasing from, where you will enter your billing and shipping information.
