A merchandise display system comprising: a tray configured to be secured to a support structure, wherein the tray includes a forward end and a rearward end; the tray includes at least one divider wall and a floor, the divider wall extending upwardly from the floor; a pusher mechanism comprising a biasing device and configured to slide along a top surface of the floor to move a product toward the forward end; and a product retaining member configured to be positioned proximate the forward end of the tray such that the product positioned on the top surface of the floor contacts the product retaining member when the product moves toward the forward end of the tray; wherein the forward end of the tray includes a notch and wherein the notch divides the product retaining member into a first product retaining member on a first side of the notch and a second product retaining member on a second side of the notch, the pusher mechanism further including: a pusher paddle having a pusher face and having an aperture in a lower portion, and a pusher floor engaged with the pusher paddle, the pusher floor extending backward from the pusher paddle, wherein the biasing device is a coil spring and wherein the coil spring is configured to pass through the aperture in the pusher paddle, and wherein the pusher floor does not extend forward of the pusher face; a rear lock system configured to lock the pusher paddle proximate the rearward end of the tray, characterised by the rear lock system comprising: a locking wall extending upward from the pusher floor, the locking wall having a ridge, and a bar engaged with a rear portion of the tray; wherein the ridge is configured to engage the bar to retain the pusher mechanism proximate a rearward end of the tray, and wherein a vertical height of the locking wall is less than a vertical height of the bar such that a rearward end of the pusher floor does not contact the floor of the tray when the pusher mechanism is in a locked position. a tray configured to be secured to a support structure, wherein the tray includes a forward end and a rearward end;
