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 duelling 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 head to the Dorset town of Sherborne for an auction. But who will buy the best items and make the most profit for their chosen charity?
