Will it be game, set and match for Ben Cooper's or Kate Bliss's team on this episode? In Box, near Bath, presenter Caroline Hawley visits the UK's only tennis ball manufacturer, where she learns about the origins of the tennis ball and how it gets its all-important bounce! Hoping to ace it at the fair are friends Helen and Marsha on the red team. Their opponents in blue are pals Clark and Michele, who are in it 'for gavels and fame'. With 60 minutes on the clock, they take a shine to a Georgian-style silver serving dish — but not the three-figure price tag! The reds' first stop is a striking pair of arts and crafts copper candlesticks, but the cost quickly snuffs out their interest in them. At Tim Weeks's auction in Wiltshire, the bidders snap up the teams' items. Will it come down to a battle of the bonus buys?
