In a bid to be crowned Britain's best young traders, teams from across the country battle it out in a series of tough trading challenges set by Saira Khan. Team Adder from Hertfordshire and Unfinished Business from Surrey travel to Scotland. Their challenge is to sell spooky souvenirs and ghoulish get-up at the Edinburgh Dungeons. The teams must decide what to buy, negotiate the lowest prices and then sell, sell, sell. But who will win the challenge, earn a place on the leader board and still be in with a chance of competing in the USA grand final?
