Wholesale companies are businesses that purchase large quantities of goods directly from manufacturers or distributors. They then sell these products in bulk to retailers or other businesses, often at a lower price than retail. This model allows retailers to stock their shelves without having to buy directly from the manufacturer, making it easier for them to manage inventory and costs. These companies play a crucial role in the supply chain, acting as intermediaries between producers and consumers. Examples of wholesale companies include Costco, Sam's Club, and various regional distributors. They help ensure that products are available in stores and can also provide valuable services like logistics and storage.
