A shopping cart or trolley, also known by a variety of other names, is a wheeled cart supplied by a shop or store, especially supermarkets, for use by customers inside the premises for transport of merchandise as they move around the premises, while shopping, prior to heading to the checkout counter, cashiers or tills. Increasing the amount of goods a shopper can collect increases the quantities they are likely to purchase in a single trip, boosting store profitability.
