On the surface, the main beneficiary of the price wars has been The Express, which costs 20p in the London area on weekdays, 25p on Saturday and 50p on Sunday. But a closer look at the numbers suggests that Richard Desmond might as well be giving cash away to every reader. On weekdays, the circulation in the Carlton TV area has risen by an estimated 26,000 to 202,000; but each of the existing readers is now saving 15p a day, which the circulation department at Associated Newspapers ( owners of the Evening Standard) calculates at a £136,000 weekly bill for Desmond. "On Saturday, they're up by 18 per cent to 260,000, but that day alone is costing £55,000 in lost revenue. And that doesn't include what they're spending on promotion and advertising." The Daily Mail, which shows no intention of cutting its price, has maintained its sales over the period.
