This chart shows the number of food price quotes that saw a change in package size in each month. Many price quotes are collected for the same item, for example “Carton/Box of Chocolates”. Price collectors aim to select products which are popular, and so it is possible that several price collectors will price the same product (a particular brand of chocolates, for example). Such a product may experience a change in size, and this helps to explain the big spike in package size reductions in April 2014, where there were 87 instances of the same item changing size.
