What is the nature and function of distribution and wholesaling?

"Distribution (place) includes the efficient managing of the acquisition of raw materials by the factory and the movement of products from the producer or manufacturer to business-to-business users and consumers. Place includes such activities as location selection, store layout, atmosphere and image-building for the location, inventory, transportation, and logistics. Logistics activities are usually the responsibility of the marketing department and are part of the large series of activities included in the supply chain. Distribution channels are the series of marketing entities through which goods and services pass on their way from producers to end users. Distribution systems focus on the physical transfer of goods and services and on their legal ownership at each stage of the distribution process. Channels reduce the number of transactions and ease the flow of goods. Wholesalers typically sell finished products to retailers and to other institutions, such as manufacturers, schools, and hospitals. Firms that sell finished goods to retailers, manufacturers, and institutions are wholesalers. The two main types of wholesalers are merchant wholesalers and agents and brokers. Merchant wholesalers buy from manufacturers and sell to other businesses. Agents and brokers are essentially independents who provide buying and selling services. They receive commissions according to their sales and don’t take title (ownership) of the merchandise. Firms that sell goods to consumers and to industrial users for their own consumption are retailers."
