The list price refers to the Manufacturer's Suggested Retail Price (MSRP). This is the price at which the manufacturer recommends that the retailer sells the product at. 

We make every effort to maintain up-to-date publisher list prices. However, we cannot guarantee their accuracy since these prices may change over time. As a result, the price printed on the book may not correspond to the current price set by the publisher, depending on when the books were received.
