Sir Alan gives the teams his toughest task yet - selling products to trade. To see if they have an eye for a money spinner, the teams must first choose their products. Selling them won't be easy as they're not allowed to approach consumers. Instead, they must try to appeal to the discerning retailer in the image-conscious world of cutting-edge design. With only one day to open trade accounts the candidates are under pressure from the start. Some products impress, but others are harder to offload, forcing the candidates to become ever more resourceful as their deadline closes in.
