Each KonaKart product object has 4 price fields that can be used to store 4 different prices. For example, these may be retail price, wholesale price, MRP, employee price etc.

The prices may be stored just for reporting purposes since whenever a product is added to an Order and an OrderProduct object is created which becomes an attribute of the Order object, this OrderProduct contains all of the product prices. This means that whenever documentation is generated from the order, you can show customers information such as the discount from the MRP etc.

The prices may also be used to display different prices to different customers based on what customer group they belong to.
