The Simons department store chain of Canada is launching a new app as part of its plan to grow its e-commerce business. According to management, it will help close the gap between e-commerce and the stores. The cost was around $3 to $4 million. Among other things, it allows users to upload a picture of a product they like and see recommendations of similar items at Simons. It also incorporates loyalty cards, tracks previous in-store and online purchases, and allows shoppers to scan tags in-store for product data. Simons is also planning a high-tech robotic DC for the future. The company operates 15 stores in Canada, mostly in Quebec, and is in the midst of a $200-million national expansion.
