Domino's Pizza has revealed what it describes as "excellent" results for last year, driven primarily by the growth in its digital sales. The company also says its franchisees were helped by a "record low cheese price, favourable wheat price and a fall in fuel costs". Pre-tax profits were £73.16m, up from £62.1m in 2014. E-commerce sales now account for 77.7% of all UK deliveries and 48.6% of online sales are made using its app. Domino's says online orders in the UK rose by nearly 29% last year and app-based orders shot up by more than 41%, with 11.5 million people now having downloaded the app in total. "The thing that customers want more than anything else is convenience and that means food that's delivered to their home," chief executive David Wild told the BBC.
