K-Mart is the third largest discount retailer in the US behind Walmart and Target. It operated over 1,400 stores but struggled with competition and management issues. These included fluctuating prices that dissatisfied customers, lack of product variety compared to competitors, and multiple changes in CEO and the board of directors that led to bankruptcy. Recommendations included focusing on local communities, franchising smaller stores, and merging with Sears to potentially become the largest discount retailer.
