Any individual who purchases products and services from the market for his/her end-use is called a consumer. In simpler words a consumer is one who consumes goods and services available in the market. In the world of today, there are countless products made available by endless providers that each, in some way, attempt to persuade consumers to purchase their specific product(s) or service(s). Some companies manufacture or provide similar, sometimes almost identical, goods and some provide differentiated products that may suit certain niche markets. Either way, consumers constantly have to choose between products and services that they want to buy based on what is felt suitable to their identity. That is, the decision of buying a specific product or service is in the end up to the individual consumer.
