Dune is extending the number of its concessions in John Lewis’ network of 26 department stores and is looking to expand toward other department stores in the UK as well. The British footwear retailer, which already opened the first 9 corners in John Lewis stores last February, is planning to add 8 in other locations including Canary Wharf, Liverpool, Reading, Sheffield, Glasgow and Peter Jones in London’s Sloane Square in the next few months.
