Did you mean drop shipping?
Drop shipping is a supply method where the retailer does not keep merchandise in stock, but simply advertises the inventory of a wholesaler and then transfers customer orders and shipment details to that wholesaler to fulfill.
It works like this: You find a drop shipper and set up an account. Different drop shippers have different setups but usually you can choose to credit your account, or, you can simply leave it empty and pay for each item as you sell it. Once you've created an account, all you need to do is grab the drop shipper's provided photos and product descriptions for the items you wish to sell and list them on eBay or your website. After you make a sale and receive payment, log into your drop shipper account, select the product you have just sold and take it through the checkout and pay for it. Enter the buyer's shipping details, and the drop shipper will package it up and post it.
Basically, the big advantage of drop shipping is that the drop shipper takes all the responsibility for handling and managing stock, saving you a heck of a lot of time.
