A drop shipper is a middle man between an online retailer and a brick and mortar store.
For example we'll use, Amazon, a commonly used Internet retail store, and Wal-Mart, a traditional brick and mortar retail store.
stores like Wal-Mart will list items on Internet stores like Amazon and
mark up the prices to allow for profit. When the Amazon customer puts
in an order for one of Wal-Mart's items, the drop shipper will purchase
and ship the item from Wal-Mart directly to the Amazon customer.
