Business-based reality show. Called to a north London warehouse, the teams are each given a pallet containing 250 pounds' worth of wholesale goods. Their task is to find out what sells best, before investing in that product. They have the whole of London to sell to - street markets, houses door-to-door, offices, and maps to help them find more prospective buyers. The trick is to match the products to the potential market, but some get it badly wrong, taking tacky stuff to snobby areas, or high-priced goods to East End pound shops. For some selling comes naturally, but for others it is a humiliating struggle. As the day draws to a close, one team receives a nasty surprise in the boardroom, and Lord Sugar's famous firing finger sends another candidate home.
