Dropshipping is where the retailer does not keep goods in stock, but instead transfers customer orders and shipment information directly to wholesalers, who then ship the goods directly to the customer.
So let's say you want to sell handbags from a certain company. You would buy the products at the wholesale price, collect the money from your customs and the manufacturer then ships it to them.
