If a product is packaged for sale in quantities of more than one, the total price must be posted. The posting must be by a label securely affixed on each item or by a label posted on the shelf edge immediately below or above the item. Compliance with this section is not required for items not marked in accordance with a uniform products code or any similar marking system designed to be scanned by electronic or magnetic checkout equipment. Any person who violates this section is guilty of an infraction.
