Choice is urging consumers to check quantity statements on similar looking products such as cereal and snacks if they want to get better value for money.
The consumer advocacy organisation says it compared a selection of similar-looking groceries including rice bubbles and laundry powder to show consumers how they can get more value at the supermarket.
Although Mission Chips and Doritos look similar, for instance, Misson Chips have an extra 55 grams of corn chips, Choice says.
Choice also notes that although Arnotts' White Chocolate Tim Tams have the same pack size and price as original Tim Tams, they contain two fewer biscuits.
“You don’t need celebrities or cartoon birds to tell you what the best buy is. If you are looking to get more bang for your buck with your weekly shop you should look past the flashy brands and bright sales signs and read the quantity statements on the front of pack,” Tom Godfrey, Choice head of media, says.
