Gregg and Chris head to Wandsworth in south London to meet dental nurse Sheena King and her daughter Nila. Work pressures mean that Sheena's go-to is pre-packed convenience food, as well as organic produce, which she believes tastes better than non-organic food. Sheena never makes a shopping list and generally spends three times more than the national average on the weekly shop, and since Nila is a picky eater, Sheena ends up cooking two separate meals every time. Can Gregg and Chris curb Sheena's spending and show her an alternative way of shopping that will satisfy her expensive tastes and Nila's eating habits and save them money along the way?
