The extension basket increases the volumetric capacity of the conventional shopping cart by providing an additional separate compartment when extended. When retracted the shopping cart is nestable with similar carts for storage in the conventional manner. The extension basket may be mounted on conventional nonexpandable shopping carts without redesign or change in the construction of the conventional cart.
