Chris and Gregg head to Amersham in Buckinghamshire to visit a former ballet dancer. Single mum Gabrielle proves to be the pair's biggest challenge to date, shopping up to three times a day, seven days a week and spending thousands. She's a shopaholic with a difference! Gabrielle isn't spending the big bucks because she loves doing it, this busy mum is doing everything she can to avoid a big supermarket shopping trip by going multiple times a day to small convenience stores, and daughter Zeeza is at her wits' end. When the pair aren't on a food run, they're at home heating up microwave food, and avoiding home cooking. With the bills spiralling into the thousands, can Chris tackle Gabrielle's supermarket phobia? Plus can Gregg find a way of inspiring Gabrielle in the kitchen, reigniting her love of food? With a weekly spend of over four and a half times the national average, and a bizarre approach to food shopping, is this the one that finally breaks our dynamic duo?
