They play a crucial role in the supply chain by providing products at lower prices due to bulk purchasing, which helps smaller businesses maintain competitive pricing. These wholesalers often specialize in specific product categories, such as food, clothing, or electronics. By acting as intermediaries, toptancılar help streamline the distribution process, ensuring that retailers have access to a wide range of products without needing to manage large inventories themselves.
