The low product indicator device may be visible when an amount of product positioned on the top surface of the divider floor or on the shelf is low. ## Claims ### Claim 1 A merchandise display system comprising: a divider configured to be secured to a support structure, wherein the divider includes a forward end and a rearward end; the divider includes a divider wall and a divider floor, the divider wall extending upwardly from the divider floor; a pusher mechanism comprising a biasing device and configured to slide along the divider floor to move a product toward the forward end; a barrier configured to be positioned proximate the forward end of the divider such that the product positioned on the top surface of the divider floor contacts the barrier when the product moves toward the forward end of the divider; a low product indicator device comprising a side wall, a front wall, and a bottom wall; wherein the biasing device comprises a coiled spring; and wherein the coiled spring passes over the bottom wall of the low product indicator device and below the front wall of the low product indicator device. ### Claim 2 (depends on 1) The merchandise display system of claim 1, wherein the low product indicator device further comprises a protruding portion, and wherein the protruding portion is configured to extend forward of the barrier when an amount of product positioned on the top surface of the divider floor is low. ### Claim 3 (depends on 1) The merchandise display system of claim 1, wherein the low product indicator device is configured to move forward with the pusher mechanism as the product nearest the forward end is removed until a predetermined amount of product is removed from the merchandise display. ### Claim 4 (depends on 3) The merchandise display system of claim 3, wherein the predetermined amount of product is adjustable. ### Claim 5 (depends on 4) The merchandise display system of claim 4, wherein the bottom wall of the low product indicator device is configured to slide under the pusher mechanism when all product is removed from the merchandise display system. ### Claim 6 (depends on 1) The merchandise display system of claim 1, wherein the low product indicator device is removably engaged with the merchandise display system. ### Claim 7 (depends on 1) The merchandise display system of claim 1, wherein the barrier is transparent. ### Claim 8 (depends on 1) The merchandise display system of claim 1, wherein the front wall of the low product indicator device may be seen through the barrier when an amount of product positioned on the top surface of the divider floor is low. ### Claim 9 A merchandise display system comprising: a divider configured to be secured to a support structure, wherein the divider includes a forward end and a rearward end; the divider includes a divider wall and a divider floor, the divider wall extending upwardly from the divider floor; a pusher mechanism comprising a biasing device and configured to slide along the divider floor to move a product toward the forward end; a barrier configured to be positioned proximate the forward end of the divider such that the product positioned on the top surface of the divider floor contacts the barrier when the product moves toward the forward end of the divider; a low product indicator device; wherein the low product indicator device is configured to move forward with the pusher mechanism as the product nearest the forward end is removed until a predetermined amount of product is removed from the merchandise display. ### Claim 10 (depends on 9) The merchandise display system of claim 9, wherein the predetermined amount of product is adjustable. ### Claim 11 (depends on 9) The merchandise display system of claim 9, wherein the low product indicator device further comprises a protruding portion, and wherein the protruding portion is configured to extend forward of the barrier when an amount of product positioned on the top surface of the divider floor is low. ### Claim 12 (depends on 9) The merchandise display system of claim 9, wherein the barrier is transparent. ### Claim 13 (depends on 9) The merchandise display system of claim 9, wherein the front wall of the low product indicator device may be seen through the barrier when an amount of product positioned on the top surface of the divider floor is low. ### Claim 14 (depends on 9) The merchandise display system of claim 9, wherein the low product indicator device is removably engaged with the merchandise display system. ### Claim 15 (depends on 9) The merchandise display system of claim 9, the low product indicator device further comprising a side wall, a front wall, and a bottom wall. ### Claim 16 (depends on 15) The merchandise display system of claim 15, wherein the biasing device comprises a coiled spring; and wherein the coiled spring passes over the bottom wall of the low product indicator device and below the front wall of the low product indicator device. ### Claim 17 (depends on 9) The merchandise display system of claim 9, wherein the bottom wall of the low product indicator device is configured to slide under the pusher mechanism when all product is removed from the merchandise display system. ### Claim 18 A merchandise display system comprising: a divider configured to be secured to a support structure, wherein the divider includes a forward end and a rearward end; the divider includes a divider wall and a divider floor, the divider wall extending upwardly from the divider floor; a pusher mechanism comprising a biasing device and configured to slide along the divider floor to move a product toward the forward end; a barrier configured to be positioned proximate the forward end of the divider such that the product positioned on the top surface of the divider floor contacts the barrier when the product moves toward the forward end of the divider; a low product indicator device comprising a side wall, a front wall, and a bottom wall; wherein the biasing device comprises a coiled spring; wherein the coiled spring passes over the bottom wall of the low product indicator device and below the front wall of the low product indicator device; and wherein the low product indicator device is configured to move forward with the pusher mechanism as the product nearest the forward end is removed until a predetermined amount of product is removed from the merchandise display. ### Claim 19 (depends on 18) The merchandise display system of claim 18, wherein the barrier is transparent; and wherein the front wall of the low product indicator device may be seen through the barrier when an amount of product positioned on the top surface of the divider floor is low. ### Claim 20 (depends on 18) The merchandise display system of claim 18, wherein the low product indicator device further comprises a protruding portion, and wherein the protruding portion is configured to extend forward of the barrier when an amount of product positioned on the top surface of the divider floor is low.
