Supershoppers S05E01 - Episode 1

Anna Richardson and Sabrina Grant take on retail giant John Lewis and show that their famous price promise can't always be believed. The programme goes undercover at a major UK high-street chain and catches their sales staff giving suspect advice that could cost customers significantly. Plus: dairy-free milks - what are you actually drinking? And how do you milk an almond? The programme also explores which batteries last the longest, and the truth about supermarket value brands.
