Sellers can operate in various settings, including physical stores, online platforms, or through direct sales. In the context of commerce, sellers can be categorized into different types, such as retailers, who sell directly to consumers, and wholesalers, who sell in bulk to other businesses. Effective selling often involves understanding customer preferences and pricing strategies to attract buyers and generate sales.
