The Booth Family

Gregg and Chris have their work cut out for them with the Booth family in Lancashire. Mum Jenny claims to always shop with a list and tries to be cautious, stocking up on buy-one-get-one-free deals. Dad Howerd's impulsive purchases mean that the food bill mounts up. They want to save £40 a week on food to afford a much-needed home extension.

Gregg and Chris get to work, secretly watching the Booths in the supermarket as they pile their trolley high, no lists or meal plans in sight. Considering the epic food shop, they expect to find the cupboards bare at home - but they find over £1,000 worth of food stockpiled in the kitchen.

After the Booths get a reality check about how much they are actually spending, all of their food labels are removed and some of their favourite products are swapped to see if they really like their brands as much as they think they do. The Booths love their sausages, so Chris heads to a sausage factory to see what the difference is between the mass-produced ones and ones from the butcher. Gregg investigates orange juice to see whether it's actually worth spending money on top-priced premium juice over concentrate.

The Booths' trial is over and they will only save if they accept enough of Gregg and Chris's swaps. Have they succeeded in changing the way this family shop forever?
