Price lists, catalogues and COD are mainly used in operating

Price lists, catalogues, and COD (Cash on Delivery) are mainly used in operating mail order businesses. In a mail order business, customers can browse through a catalogue or price list of products, place an order by mail, phone, or online, and then pay for the products upon delivery through COD. This method allows customers to shop from the convenience of their own home and provides businesses with a wider reach for potential customers beyond their physical location. The products are then shipped directly to the customer's address, eliminating the need for them to visit a physical store.
