Which of the following is a feature of mail order business?

A feature of mail order business is that it practices self-service. Mail order business involves customers ordering products through mail or online, without visiting a physical store. As a result, there are no shop assistants available to provide assistance or customer service. Instead, customers browse catalogs or websites and place orders themselves, usually by filling out an order form or adding items to an online shopping cart. This is known as self-service. Mail order businesses typically have a large inventory of products and rely on the self-service model to keep costs low and prices competitive. Overall, self-service is a key feature of mail order businesses and is what sets them apart from traditional brick-and-mortar stores.
