Starbucks is the leader in retailing and roasting of specialty coffee in the world. Major competitors include Costa coffee, Caffé Nero, Seattle's Best Coffee and secondary coffee providers such as McDonald's, Burger King and Dunkin Donuts. The competition is nowhere near to Starbucks volume of operations and sales.
Consumption of coffee is not dependent on the price of the product but also on the differentiation between each product and several value adding variables such as the quality of customer services, brand, brand recognition and image of the company. Hence, Starbucks is not majorly sensitive to movements of other firms in this segment.
