A rack system for displaying products comprises a rack unit supporting some of the products so as to be accessed at a forward facing product dispensing face. The rack unit has a side portion facing generally perpendicular to the dispensing face. A corner member is supported on the side portion and comprises a first wall portion extending generally forwardly to a vertical edge adjacent the product dispensing face, and a second wall portion extending generally laterally outward from the side portion to a second vertical edge. The first and second edges each have a retaining portion extending vertically. A flexible signage member is supported on the corner member in a flexed condition between the retaining portions with a signage surface that is concave outwardly between the retaining portions. The signage member is supported and retained on the corner member by a biasing of the signage member to extend wider than a distance between the retaining portions.
