An example adjustable product display apparatus is provided that includes a body configured to be mounted to a shelf. The body includes a proximal end, a distal end, a bottom surface extending between the proximal end and the distal end, and a top surface extending between the proximal end and the distal end at an angle relative to the bottom surface. The top surface is configured to support one or more products thereon. A distance between the bottom surface and the top surface increases from the proximal end to the distal and the distance at the distal end of the body defining a rear height of the body. The adjustable product display apparatus includes an expandable support disposed at the distal end of the body. Adjustment of the expandable support varies a height of the expandable support and simultaneously adjusts the rear height of the body.
