Gregg and Chris are with the Austen family from Sussex, tackling the highest expenditure on food they've ever encountered. Mum Denise has recently had to give up work, which means the family income has reduced by a third, and yet she still raids the supermarket like she's earning her old salary. The family are guilty of stockpiling food to the point where they can't open the fridge door without items falling out. On top of that, they're utterly devoted to high-end brands, and their shop needs to include gluten-free items as Denise has been medically diagnosed with coeliac disease.
