Thrifty parents are fighting off the effects of the recession by snapping up everything from second-hand uniform to musical instruments online.
Schoolstrader.com, established in 2006, caters exclusively to parents sending their children to private schools.
But with parents handing over around £10,000 a year per child in fees, trading online may be a way of saving money in other areas.
Primaryschoolstrader.com, which launched last year, caters for families with children attending 25,000 state primary schools around the country.
Items for trading
Favourite items to trade or sell on the two sites include musical instruments, sports kit, toys, holiday homes, pets, tuition and uniform.
But there are some more unusual items up for grabs, including a pony for £500, a six-bedroom house in Dorset for £495,000 and even two free pet cats, named Stig and Inga.
