Mary Portas, presenter of hit series Mary Queen of Shops, embarks on her toughest challenge yet, increasing the potential fortunes of Britain’s charity shops. In the brand new three-part series, Mary Queen of Charity Shops, Mary takes on charity shop brands in order to transform them into must-stop-shops on the high street. As well as focusing on how the outlets themselves operate, she must also tackle the public’s perception of charity shops and influence how consumers make their purchasing decisions. From well-worn woollies to last season's fashion faux pas, charity shops have a sales challenge like no other - to turn other people's cast-offs into stock that will sell.

With strong competition from low cost fashion chains, the declining quality of donations, and the general stigma some attach to buying second-hand, it can be tough to even tempt people through the door.
