A shopping cart has upper, lower and intermediate frames. The frames have a front, rear, sides, two front corners and two rear corners. The lower and intermediate frames each have a rigid screen. Four upper posts couple the front corners of the upper and intermediate frames. Two rear posts couple the rear corners of the upper and intermediate frames. Two lower posts couple the rear corners of the intermediate and lower frames. Each of the posts has a midpoint with a hinge dividing each post into an upper segment and a lower segment. Each hinge is adapted to be pivoted between a linear orientation and a non-linear orientation. In the linear orientation the segments of the posts are perpendicular to the frames and the shopping cart is in an expanded orientation. In the non-linear orientation the segments the post are parallel with the frames and the shopping cart is in a contracted orientation.
