Experian, the information company, has announced its sale of price comparison site PriceGrabber has fallen through in acrimonious circumstances.The $175m disposal was announced back in May, but Experian says the purchase deadline has now passed and that it believes the putative buyer, Indian outfit Ybrant Digital, is "in breach of contract". PriceGrabber, which operates in both the UK and US, was put up for sale alongside a US focused lead generation business known as LowerMyBills.Experian says it continues "to explore options to sell the businesses".The group's share price was down 1% in early trading.BS
