Drop-ship / Drop-shipping: A fulfillment method where a store does not carry any product inventory. Instead, when a store sells a product, it purchases the item from a third party (i.e. a wholesaler) and has it shipped directly to the customer. The way this business model makes money is through the profit margin of the product, minus the cost of goods and the cost of advertising.
