An expandable shopping bag system is provided with a pouch capable of unfolding to a shopping bag. The first pair of opposing sides and the bottom of the shopping bag have a first set of expansion panels, allowing the bag to expand and provide additional volume. A shopping bag kit is provided with an outer bag and a plurality of inner bags, wherein the inner bags are collapsible for storage within the outer bag when not in use. The inner bags form a coordinated design when the plurality of inner bags are placed adjacent to one another. An expandable shopping bag system is provided with a bag having a bottom with a fastener. A first and second pair of opposing sides extend from the bottom to form a storage compartment. The bottom folds about the sides creating a packet.
