Retail involves the sale of goods and services from businesses and individuals to end users. Retailers purchase products in large quantities from manufacturers and then sell smaller quantities to consumers for a profit. Retailing can occur in fixed locations like stores or markets, through door-to-door sales, or delivery. There are many types of retailers including independent stores, chains, franchises, cooperatives, convenience stores, supermarkets, department stores, discount stores, catalog/telephone retailers, vending machines, and e-retailers. Retail formats range from small mom-and-pop shops to large hypermarkets.
