US Patent 10952550 Flexible row count card tier

A flexible row count card tier for attachment to a retail greeting card display unit. The flexible row count card tier contains both permanent card rows and flexible card rows. The flexible row count card tier may be adapted to have a differing number of card rows by opening or closing one or more of the flexible card rows. Closing a flexible card row creates one less row but increases the depth of the card row directly below the closed flexible card row. The number and depth of rows can be adjusted depending on the merchandising and card density need per season or retailer productivity.
