Best Buy is the largest consumer electronics retailer in the United States, with fiscal 2019 sales of nearly $43 billion. The company competes aggressively on price with such rivals as Costco, Sam's Club, Walmart, and Target, but it is also known by consumers for its first-rate customer service. Best Buy customers have commented that the retailer's sales staff is exceptionally knowledgeable about the company's products and can direct them to the exact location of difficult-to-find items. Best Buy customers also appreciate that demonstration models of PC monitors, digital media players, and other electronics are fully powered and ready for in-store use. Best Buy's Geek Squad tech support and installation services are additional customer service features that are valued by many customers. How would you characterize Best Buy's competitive strategy? Should it be classified as a low-cost strategy? A differentiation strategy? A best-cost strategy? Also, has the company chosen to focus on a narrow piece of the market, or does it appear to pursue a broad market approach? Explain your answer.
