Tips for finding used math textbooks online include searching for the ISBN numbers to compare prices and making purchases as early as possible. Price difference can vary considerably from one retailer to the next, and buying used textbooks at the last minute is often more difficult and expensive. Another tip is to check and see if local schools and retailers have a buy-back program for used books.
One of the best ways to find used text books is to visit a local on-campus bookstore to obtain the ISBN numbers and prices for both new and used volumes. This information is then used to shop online to find the best deal or value. Many online sites and services can provide price listings from multiple online retailers once the ISBN number has been supplied. Another tip for finding used textbooks is to check bookstores and services that offer book rental programs.
Other tips for finding used math books are to speak with instructors or professors who may be able to supply recommendations. Many online retailers offer international editions of textbooks at lower prices than domestic editions. Digital versions of math textbooks are also available for online purchase and are typically more affordable than printed books.
