Gregg Wallace and greengrocer Chris Bavin help families across the UK sort food fact from fiction and eat well for less. Gregg and Chris are in Chelmsford, Essex to help the Thomas family, a couple whose completely different shopping styles are causing arguments in the supermarket aisles. Newlyweds Mandy and Adie have four children between them. Brand-loving Mandy admits to having 'champagne taste with a lemonade income' - she never says no to the kid's food requests and, as a result, they go through 70 bags of branded crisps a week. Adie, however, thinks budget versions are just as good. Mandy also relies on convenience microwave meals whereas Adie likes to cook from scratch, leaving this couple completely at loggerheads. Can Gregg and Chris help them find a middle ground and potentially save them thousands a year?
