The Apprentice (2005) : 7x10

Called to a north London wholesale warehouse, the teams are met by a nostalgic Lord Sugar, who tells the teams that it was from places like this that he started out buying low to sell high. He gives both teams a pallet carrying 250 pounds' worth of wholesale goods. They must find out what sells best, then re-invest in those products. It is a simple exercise in following the money and increasing sales. The pallets contain cheap nodding dogs, pricey pressure washers, duvet sets, cut-price sunglasses, brollies, watches and more. The prospects for the task look good, and there are quick volunteers for the team leader roles. They have the whole of London to sell to: street markets, houses door-to-door, offices and maps to help find more. 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's a humiliating struggle.
