Retail trade is the resale (sale without transformation) of new and used goods to the end-user for personal or household consumption by general dealers, specialized retailers, and non-store retailers. General dealers include department stores, hypermarkets, and supermarkets, shopping centers, convenience stores, hard discounters as well as second-hand stores. Specialized stores include clothing stores, grocery stores, drug and beauty stores, book, music and video stores, newsagents, home and furniture stores, and gas stations. Non-store retailers reach the end user through direct-response advertising, paper and electronic catalogs, door-to-door solicitation, in-home demonstration, and selling from street vendors and vending machines. Retail trade excludes personal and household good repair.
