A Warehouse Club is a retail store that sells a wide variety of products in bulk at discounted prices. These clubs typically require a membership fee for customers to shop there. They offer items ranging from groceries to electronics, often in larger quantities than traditional stores, which helps to lower costs. Members of a warehouse club can save money by purchasing items in bulk, making it a popular choice for families and businesses. Some well-known examples of warehouse clubs include Costco and Sam's Club. These stores often have limited selections but focus on high-quality products at competitive prices.
