This edition features the Harveys in Nottingham, who have lost control of their weekly spend. Mum tends to go overboard on portion size by catering for what seems like 40 people rather than her family of four. Dad feels that leftovers are unappealing, meaning that this family could potentially save themselves a lot of money. Matt cooks the Harveys a delicious fish curry and a Mexican feast - both for under five pounds. Susanna sees how the luxury end of super-cheap food fares by taste testing prosciutto.
