One of Britain's favourite TV presenters has been put up for sale on eBay. Bidders looking to purchase their own Countdown countess have until tomorrow to buy the limited edition Carole Vorderman. The ad reads: "1 Original, Shrinkwrapped Carol Vorderman. Mint Quality. "Only 200 ever made (The Other 199 are now presenting TV Shows), this is an ultra-rare Collectible that should never be removed from the packaging." You too can bid for Calculatin' Carol here. The auction closes tomorrow but Ms Vorderman has already passed her reserve price and received a bid of £250. Earlier this year Ms Vorderman shut down her own Web site because it was attracting lewd and irreverent comments. ®
