Denise Van Outen presents this social experiment that sees proudly picky families swap their favourite supermarkets for a week of living exclusively off the bargain stores. First up are the Phillips family from Kent, who are challenged to ditch their premium 'big shop' and live off one discount store for a week. From mealtime favourites to laundry staples and beauty buys, every corner of the household is put to the test as they swap pricey products for purse-friendly alternatives.

Denise Van Outen heads to Holywood, Northern Ireland, to meet the Beimers - a health-conscious family who cannot live without their supermarket favourites. But for one week, they swap their usual shop for bargain stor alternatives, comparing everything from fresh food and wellness buys to household staples and hobby supplies. Mum Aimee rethinks her views on health supplements, there's fun on the shop floor with a 10-minute budget-busting challenge and the week ends with a barbecue where the family use only their bargain buys.
