A couple of weeks ago I sold an item on Ebay, which made me directly a part of Ebay’s supply chain. By using their platform for advertising my product, I was able to find a buyer with whom Ebay put me directly in contact with. Once the transaction was done, I sent the purchased items via post to the costumer. I essentially sent the “raw materials” to Ebay, they provided me with a service to advertise the product and find a buyer; and finally I organised the transportation of the sold item after Ebay (and Paypal) had taken their share of my profits.
