The One Show presenter Alex Jones and business journalist Steph McGovern return to help more families change the way they shop. In the first edition, they meet Evesham couple John and Caroline, who have eight children ranging in age from 20 years to 20 months old. With 10 people living under one roof, Caroline and John are already super-savvy when it comes to spending, but they are discovering that as the kids get bigger, so do the costs that come with them.

This week Alex and Steph are in North Lincolnshire with the Miller family. Wes and Mel have three children: Romeo, Ceci and Ronnie. They love hosting parties, and there's one extra special party that they need to save for - after 10 years together, Wes finally popped the question and asked Mel to marry him. But with no savings and big wedding expectations, they need to make considerable changes if they want the wedding of their dreams. Can Alex and Steph show these big spenders that it is possible to create memories without breaking the bank, and help them put money aside for their special day?
