Two well-known experts from the world of antiques go head-to-head over a week of challenges to find out who can make the most profit from buying and selling antiques - all of which will be donated to a charity of their choice. The dealers are in a different buying location each day: an auction house, a car boot sale, a foreign antiques market and a UK antiques fair. They must then sell their purchases for as much money as possible. On Friday, the dueling dealers compete in the ultimate challenge - The Showdown - where at least half of their items must be sold at the Showdown auction. Once the deals are done, one expert will be crowned the Put Your Money Where Your Mouth Is champion.
Mark 'The Maverick' Stacey and Mark 'Franksy' Franks face their greatest challenge yet - the Put Your Money Where Your Mouth Is Showdown. They are challenged to dig deep at four different events - to find antiques and collectibles they can sell on for maximum profit, with the added twist of the Showdown Auction.
