Shelf channel product marking system and method

A method of marking retail products displayed on product shelves that have plural shelf channels for receiving product markers, wherein each shelf channel has a channel length that shares a length multiple, which is lowest common denominator of the plural channels lengths, utilizing a bulk product marker configured as a continuous strip of material having a width selected to fit the plural shelf channels, and having plural tear lines oriented transverse to the continuous length, which are spaced apart by a strip length that is an integer divisor of the plural channel lengths, the method comprising the steps of:

• selecting a shelf for a particular product;
• determining a channel length for the selected shelf;
• determining that one or more strip lengths of the bulk product marker are equal the channel length;
• tearing the bulk product marker at a tear line corresponding to the determined channel length, thereby obtaining a product marker having a length matching the selected shelf channel length;
• inserting the product marker into the selected shelf channel.
