When Iain Sisson spotted an oil stain on a cycling jersey for sale on second-hand clothes app Vinted, he knew he could score a bargain. "I probably got an £80 jersey for the princely sum of £12.50," he says. "Obviously the previous owner didn't know the trick of using a bit of bicarbonate of soda and washing up liquid, which meant the stain came right out."
Sisson, who runs YouTube channel @mercurialcyclist, has saved himself thousands of pounds buying cycling kit second-hand online. It's particularly lucrative when the item has a fault, he adds, as it means you have more negotiating power with the seller.
