Nobody has to pay the list price for books any more.
There are several big booksellers on the web and dozens of smaller ones, all boasting deep discounts on selected features and best sellers. However, the online prices vary from dealer to dealer, sometimes by several dollars. So it pays to comparison-shop. If the company's price isn't already the lowest, it will automatically reduce the price to beat the competition. Acses is a book finder and comparison shopper that automatically visits multiple online stores and compares their prices and services.
