To me these are known as traditional Bib Tags. The upper portion identifies the product and the “everyday price.” The lower portion offers extra savings and a promotional kick. When the promotion ends, one just tears off the bottom portion and the “everyday price” remains in place and in play. Modern shelf edge label holder systems allow use of plain paper labels saving the cost of expensive self-adhesive stock and tear-off perforation. The best of these shelf edge label holders also provide a built in grip clip for quick attachment of promotions like this Bib Tag. Plain paper card stock is just inserted in the grip in an instant, and removed even quicker. A tear off top can still be used and dropped into the regular label holder window beneath the grip clip.
