Describe the differences between a wholesaler, a distribution center, and a fulfillment center.

A wholesaler is a firm engaged in buying, taking title to, often storing, and physically handling goods in large quantities, then reselling the goods to retailers or industrial or business users. A distribution center is a facility for the receipt, storage, and redistribution of goods to company stores, may be operated by retailers, manufacturers, or distribution specialists. A fulfillment center is a warehouse facility used to ship merchandise directly to consumers.
