A modular merchandising display system which, for example, allows for the ability to easily mount and remove samples of household hardware products (e.g. cabinet or bath hardware) and visualize the hardware mounted to e.g. kitchen or bath cabinets, by allowing a person to remove the sample hardware and hold it up to e.g. kitchen or bath cabinets. The display system includes at least one slat wall piece, at least one display channel on a first side of the slat wall piece configured for displaying at least one item and for providing interchangeability of the displayed item; and at least one frame piece framing the at least one slat wall piece.
