You are where you are now.
From here just keep it in your head that your contract is with the supplier. The supplier is the Principal who has to supply on your orders. He could have delivered the item himself.
He chose to use a Courier. The Courier is the supplier's Agent. A Principal is responsible for the actions of his Agent.
