RetailPriceList is a list of retail price items. A retail price item contains a coffee name, a wholesale price per pound, a retail price per pound, and a supplier. This data is used for two purposes: it contains the price list presented to the end user and is used by CheckoutFormBean when it constructs the suborders dispatched to coffee suppliers.
RetailPriceList first calls the URLHelper.getEndpointURL method to determine the JAX-WS service endpoint. It then queries the JAX-WS service for a coffee price list. Finally it queries the SAAJ service for a price list. The two price lists are combined and a retail price per pound is determined by adding a markup of 35% to the wholesale prices.
