This week they are in Essex with the Evans family, who rely on ready-made sauces and packets for their meals and make nothing from scratch. Desperate to save money and take their children on holiday, Matt shows them some fantastic family favourites - each for under a pound a head - to get them cooking and saving. With a classic fish pie and a delicious chicken curry the Evans' cooking habits are transformed. Susanna is taste testing cola, pitting a super-cheap brand against Coke to see which shoppers prefer. Also, as many favourite snacks seem to have fallen victim to 'shrinkflation' - being charged the same amount for smaller packets, Susanna investigates how we can fight back and beat the shrink.
