It also has its gradations: Shop specialization (eg, sales of men's shirts), store a limited range (eg, men's clothing), a shop full of a separate range (for example, a clothing store or shoe for men, women and children). Department stores sell several different groups of goods: clothing, footwear, furniture, household goods, haberdashery, stationery, etc. Each of these groups has its own department, which deals not only trade but also the purchase and storage of goods. The main principles underlying the organization of the first stores: goods are put up for public display, easily accessible to explore and encourage the person to make a purchase, better service, relatively low prices and the resulting rapid turnover of goods. Facing increasing pressure from competitors, especially discount stores, Department stores are forced to shift, coming up with new tricks to attract the mass buyer. One of the characteristic methods is the appearance of large department stores so-called "bargain basement". Supermarkets – large self-service stores selling a wide range of food products, as well as some basic goods (primarily economic). For supermarkets characterized relatively low trading costs due to the large volume of sales and the associated rapid turnover of funds, as well as the use of standard facilities and equipment, small machines (for cutting, packaging and Weighing goods) recently been developed combined stores, which combine the sale of food and other consumer goods, such as drugs.
