Drugstore chains are retail stores that primarily sell prescription medications, over-the-counter drugs, and health-related products. They often offer a variety of items, including personal care products, cosmetics, and household goods. Many chains also provide additional services, such as pharmacy consultations and health screenings. These stores are typically found in urban and suburban areas, making them easily accessible to customers. Popular drugstore chains in the United States include CVS, Walgreens, and Rite Aid. They play a crucial role in the healthcare system by providing essential medications and health services to the community.
