The astonishing success of pizza delivery firm Domino's Pizza has continued since the start of the year, with the company reporting a 10.5% rise in like-for-like sales. The group said it has had a strong start to 2010, despite the adverse weather conditions in the early part of the year. System sales were up 17.5% in the 13 week period ended 28 March to £118.9m and like-for-like sales for the period in 553 mature stores were up 10.5% (2009: 9.3% in 501 mature stores). E-commerce continued to grow strongly with sales online for the period up 52.3% to £25.3m (2009: £16.6m) and accounted for 28.8% of UK delivered sales (2009: 23.6%). Domino's has opened eight new stores since the beginning of the year (2009: 10 new stores), bringing it to a total of 616 stores as at 28 March 2010 (2009: 563), and said it is well-positioned to achieve its target of 55 new store openings this year. Chief executive Chris Moore said: "We are delighted with our like for like sales performance, which comes despite the snow in the early part of the year forcing many of our stores to temporarily close. We face some incredibly tough comparatives in the second half of the year, but we have the people, the product, and the plans to continue to deliver excellent results in the coming months. "We are pleased with our current performance and trading continues to progress in line with expectations."
