A wholesaler is a business or individual that purchases large quantities of goods directly from manufacturers and sells them in smaller quantities to retailers or other businesses. This process allows wholesalers to take advantage of bulk pricing, which helps them offer competitive prices to their customers. Wholesalers play a crucial role in the supply chain by acting as intermediaries between producers and retailers. They help distribute products efficiently, ensuring that items like electronics, clothing, or food products reach stores where consumers can buy them.
