Two teams – designated the "Reds" and the "Blues" – compete. Each team has two members, who wear fleeces that correspond to their team's colour. The contestants in most episodes are members of the public, though some shows feature teams of celebrity players instead. At the beginning of the show, each team is given a set amount of money with which to purchase antiques. The objective is to find items that will earn the team a profit when later sold at auction. Each team is accompanied by an antiques trade expert, though it is the contestants' decision whether to heed the advice given by their expert. After the contestants have completed their purchases and presented them to the host, home viewers are shown a "what the auctioneer thinks" segment in which the auctioneer appraises the buys and gives the auction estimate. At the auction, as each item is sold, the host compares the auction sale price to the price originally paid by the team, with the difference being either subtracted from or added to the team's total. If the final total shows a profit, the team receives that profit in cash; otherwise, the team receives nothing. The profit/loss does not take into account commission (buyers' premium) or VAT (Value Added Tax, a governmental sales tax).
