The June 2023 grocery basket marks a year since we started collecting and comparing grocery prices. We started collecting prices for four stores and now collect eight. Last year sunflower oil saw a large price increase as a result of the Ukraine war, poor climate conditions and poor harvests. Ukraine and Russia are the two largest producers of sunflower oil in the world. A year later the sunflower oil is one of the few items in our basket that has decreased in price compared with a year ago.
