A fluid dispensing system (10) includes a pump assembly (40) for pressurizing a low cost container (20), the container (20) non reversibly connected to a coupler module (100). A wand assembly (80) is releasably connected to the coupler module (100). A discharge conduit (60) fluidly connects the wand assembly (100) to the container (20). The wand assembly (100) includes a grip body (82) slidable relative to the discharge conduit (60) between a retracted storage position and an extended operable position. The coupler module (100) is connected to a skirt (120), the coupler module (100) including a mating surface (102) for releasably retaining the grip body (82). The coupler module (100) is injection molded and The container (20) is a blow molded pressure vessel. As a blow molded component, the container (20) is relatively inexpensive compared to an injection molded container of a comparable size.
