A retailer is a business or individual that sells goods or services directly to consumers for personal or household use. They act as the middleman between manufacturers or wholesalers and the end consumer, offering a wide range of products in physical or online stores. Retailers play a crucial role in the economy by providing convenient access to goods and services, as well as creating jobs and stimulating competition. They are responsible for sourcing, pricing, marketing, and selling products to meet the needs and desires of their target audience. Successful retailers possess strong customer service skills, a deep understanding of market trends, and the ability to adapt to changing consumer demands.
