This episode exposes the truth about some of the dubious selling techniques of many high street fashion stores. Super sellers James and Megan take over a Liverpool fashion outlet to give a master class in the upsell. Restaurant manager Neil Gill shows how a £2.50 chicken kebab can be sold on successfully for £10.50, using what consumer pyschologists call 'the crowd principle'. Harry then puts this to the test at a local car sale. And super seller Lauren shows how easy it is to sell off counterfeit iPhones and chargers from a market stall.
