Food Inflation Tracker shows that the price of food and drink is continuing to soar, as people suffer through the worst cost of living crisis in decades. It's no surprise to see many shoppers turning to discounters like Aldi and Lidl when our research shows they could make savings of more than £18 on a basket of everyday groceries.
