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?
