Alex and Steph head to north London to meet Kevin and Yolanda. This shopping-obsessed couple are desperate to save some money for their upcoming wedding. Having recently lost 16 stone between them, new-found confidence has led to a shopping obsession, each of them buying new clothes to flatter their new frames. To reveal just how much stuff there is, Alex and Steph have gone into the house and taken their possessions to stock a pop-up shop. Yolanda and Kevin can't believe it when they walk in and find everything out on display. When they are confronted with how much they have spent, they are left shocked. Alex and Steph swap Kevin and Yolanda's products for unbranded substitutes to show where they can spend less, but not all the products have been changed. Will they be able to spot the difference? And will they make the changes needed to save for their wedding?

Alex Jones and Steph McGovern are on a mission to help families change the way they shop without changing their lifestyle. They are in Surrey with John and Flo and their three children. A drop in income coupled with a reliance on credit means the family need help to get back in the black. The sooner the family start reining in their spending the better, so Alex and Steph debrand their home, replacing many of their favourite products with cheaper alternatives.
