KitKat chocolate confectionary bars, manufactured by Nestle SA, sit displayed for sale in a newsagent's store in London, U.K., on Thursday, Oct. 17, 2013. The cost of chocolate is set to rise, propelled by raw sugar trading at a nine-month high and this year's 60 percent increase in cocoa butter combined with the arrival of Christmas demand.
