The final four celebrities, now competing as individuals, have to sell the impossible by adding value to a pile of items normally considered to be unsellable assigned to them at random, and selling them at a local market. The celebrity that earns the most money at the market wins A$20,000 for their charity and a place in the grand final, while the losing celebrities return to the boardroom, where they each plead their cases before Lord Sugar chooses one of them to take the other place in the grand final.
