A price book is a list of products and their prices that can be added to an opportunity. A product can have different prices for different markets or segments, and these prices are stored in different price books. In this case, the administrator should create a new price book for the new retail pricing and add the products that are sold to retail locations for resale. This way, the users can select the appropriate price book and products for their opportunities based on the type of customer they are selling to.
