Confronting families with out-of-control spending, shopping experts are on a mission to change the way they shop without changing their lifestyle. From make-up and cleaning products, to gadgets and clothes, they’ll replace their usual products with unlabelled ones, usually cheaper but sometimes more expensive, to challenge their loyalty to certain brands. They’ll also investigate where products come from and reveal marketing tactics, helping us all to shop smarter. At the end of the experiment, the family finds out which products they’ve been using. Can they admit their shopping sins, change their buying habits and save a fortune?
