A second embodiment includes a spring-clip that attaches to a side wall of the RPC and a sign holder that is oriented at a predetermined angle. A third embodiment includes an elongated spring-clip that attaches to a side wall of the RPC and an elongated, angled sign holder that is designed to hold signs that are scored along its length. A fourth embodiment sits in the interior volume of the RPC, divides the interior of the RPC into four compartments for different types of produce, and provides a sign holder for each of the four compartments.
