Pricing data compiled by comparison website CW Scanner shows the supermarket chain raised prices on at least four key products after the promotion started on 1 May. The items identified include chicken fillets, potatoes and donuts.
The 'Price Freeze' promotion was advertised as a way to help customers with the cost of living by locking in prices on hundreds of everyday items for three months. The data suggests that at least some of those prices were not in fact frozen.
The exclusive analysis, first reported by Guardian Australia, raises questions about the accuracy of promotional claims made by Australia's largest supermarket chain during a period of heightened consumer sensitivity to grocery costs.
