A four-wheel shopping cart includes a substantially rectangular base surrounded by vertical side, front and rear walls to form an open-topped, cargo basket. The front wall opens fully to provide access to the cargo area, while the rear wall is shorter than the others to allow easy access from behind while shopping. A transverse axle mounted below the rear wall supports hinged legs that fold upwards alongside the side walls so the cart can be placed conveniently into a vehicle for transportation. The legs unfold and lock to support the cart on castors for shopping, and may include height adjustment means for lowering the basket to a comfortable level for usage and for raising it to place it into the shopper's vehicle. A pair of small, adjustable wheels mounted on opposite front corners of the base pivot partially to facilitate maneuvering the cart within the vehicle.
