Abstract: A price tag display holder and support arm device for use with a peg-bar display of peggable packages which are arranged in both vertical and horizontal rows without appreciable spacing between the vertical and horizontal edges of packages in adjacent rows. The device has a strap-like support arm which is upright or on edge in use. The support arm has a proximal end which is connected in cantilever fashion to one of the vertically spaced horizontal peg supports located at the rear of the packages and a distal end on which a price tag display holder is mounted. The support arm is of adjustble length to permit an adjusted length that places the price tag display holder for viewing by a customer looking in the direction of the aisle. The strap-like support arms of the devices are sufficiently thin so as to permit the arms to be squeezed in between packages in adjacent vertical rows.
