Supermarkets provide petrol (gas) at sites outside their stores. They cut the petrol price to a level lower than that of other suppliers in order to draw in more customers, who then buy more items in the store when they purchase more petrol. If this plan succeeded, how would it be shown on demand and supply diagrams?
