An expandable cart apparatus includes a cart that has a bottom wall, a front wall, a back wall, a first side wall and a second side wall. The cart includes four vertically orientated corners each defining a post with an open upper end. A plurality of wheels is rotatably coupled to the bottom wall. A loop has a generally rectangular shape and includes a pair of lateral portions and a pair of end portions. Each of a plurality of secondary walls is attached to and extends downwardly from one of the lateral and end portions. Each of a plurality of rods is attached to the loop and extends downwardly therefrom. Each of the rods is extended into one of the upper ends of the posts. The rods are selectively positionable with respect to the posts so that each of the secondary walls is positioned outside of the cart.
