Product distribution (or place) is one of the four elements of the marketing mix. Distribution is the process of making a product or service available for use or consumption by a consumer or business user, using direct means, or using indirect means with intermediaries. Distribution of products takes place by means of channels. Channels are sets of interdependent organizations (called intermediaries) involved in making the product available for consumption. Merchants are intermediaries that buy and resell products. Agents and brokers are intermediaries that act on behalf of the producer but do not take title to the products.
