Price per kilo of large formats is sometimes more expensive, in reality, than the same product in standard packaging, says Foodwatch. Foodwatch, alerted by consumers "annoyed to find again and again this practice in supermarkets", has "checked in the drives and shelves of the main chains of mass distribution" Foodwatch estimates that "every extra penny paid per kila or liter on a special format is one cent too much" "These abuses should be prohibited or strictly controlled as promotions are," Foodwatch campaigner Audrey Morice says.
