There is disclosed a module for a modular transport & display unit for transporting products to a store and for then displaying said products in said store. The module comprises a shelf adapted to receive said products thereon and at least one reconfigurable support structure. Said at least one reconfigurable support structure is adapted to be deployed to support one or more additional modules that will collectively form, when so supported, together with the initial module, the modular transport & display unit. Said at least one reconfigurable support structure is also adapted to be stowed away within said shelf, so that each module, and, therefore, the modular unit, can be straightforwardly disassembled by a store operator for return to a logistics centre, without damaging any components.
