Abstract: A plastic shopping cart is disclosed. In accordance with certain aspects of the present invention, all of the components of a shopping cart are formed from a moldable material such as, for example, a thermoplastic resin by means of an injection molding process or the like. When shopping cart (66B) is being inserted inside shopping cart (66A), the front portion of basket (30B) causes the gate and seat assembly (36A) to be disposed in a fully raised position. This causes the handle (34) of the shopping cart (66) to travel up the inclined portions (60) of the cam members (58) of the gate and seat assembly (36A) and, therefore, lift the rear caster wheels of the shopping cart (66) off of the ground.
