Which of the following retail outlets is described as selling without shops

The retail outlet that is described as "selling without shops" is a mail order business. Mail order businesses do not have physical storefronts or shops that customers can visit to browse or purchase products. Instead, customers place orders through mail, phone, or online, and the business ships the products directly to the customer's address. This type of retail business model is particularly popular for items that are not easily found in local stores or for people who prefer the convenience of shopping from home. Customers can view product catalogs or websites, place orders, and make payments online or via mail without having to physically visit a store.
