Buyoncegivetwice.co.uk aims to persuade people who have not collected items they have won in charity auctions to donate them for resale. The original charity will receive 60 per cent of the resale price and 30 per cent will go to the new purchaser's favourite charity. The remaining 10 per cent will cover the site's running costs.
Charities will also have the option of re-auctioning lots directly to receive 90 per cent of the resale value. The remaining 10 per cent will cover the site's costs.
The Juvenile Diabetes Research Foundation auctioned the first lot on 1 February. A three-day trip to the Italian Alps to watch World Cup Skiing, with flights and accommodation for two, is the prize on offer.
The site will launch fully on 17 April.
