Some old DVDs that you've seen a million times, a jacket with the elbows worn out, a pair of wellington boots... a Formula 1 race suit worn by Ralf Schumacher - you just never know what you're going to find in a charity shop!
Incredibly, a store that raises funds for disabled people in the town of Kenilworth could be sat on one of its most lucrative donations - a full Williams race suit worn by the German driver.
It is now known who donated the suit, or why, but the BBC, who took a trip to the store to find out more, report that it could be worth as much as £2,000 at auction.
The red suit, coloured by Williams' sponsorship from Winfield cigarettes in 1999, was worn by Schumacher in his debut season at the British team.
Schumacher scored a podium on his Williams debut in Australia, going on to secure further top-three finishes in Great Britain and Italy as he finished the season sixth in the world drivers' championship.
