Monty enters into an agreement to deliver some wine to a customer through their online service. The customer chooses some wine and arranges for that wine to be placed on their front door step if no one answers the door. The wine is duly delivered with the customer's credit card duly charged. The wine is placed on the front door step at 10 am in the morning by a courier. The wine is clearly on display to the street. The customer arrives home quite late and finds that the packaging of the wine has been opened, several bottles are missing and others have damage to their labels since someone used a knife to open the box. The customer believes the wine should have been placed less conspicuously on the front step where it could not be seen, rather than so prominently at the top of the steps. The customer informs the supplier that he does not believe he should pay for all of the wine since the courier used by the supplier is at fault in the way the wine was delivered. What are the rights and liabilities of the customer in this situation in the light of the Sale of Goods legislation?
