This new series provides an eye-opening and intriguing look at how we shop, which products we buy, and what its 6.7 billion-a-week shopping habit says about Britain today. Each episode, Mary Portas meets the high street buyers, trend forecasters, celebrity endorsers and the great British public - to discover what's flying off the shelves and what's not shifting. Armed with inside information from the nation's biggest retailers - including M&S, Amazon, Waitrose, Superdrug, Halfords, Waterstones, John Lewis, and more - What Britain Buys lifts the lid on what we spend our hard earned cash on and why. So if you are wondering why adults are playing Lego, don't know why your bathroom is overrun with male beauty products, have never tried a freakshake, or wondering why the great British cuppa is facing competition from coconut water, Mary provides the answers you need.
