MyWebGrocer.com sets up supermarkets with their own virtual store. The company doesn't sell or deliver the food itself; it forms partnerships with existing grocery stores and provides those businesses with online capabilities. The particulars -- home delivery or in-store pick-up, etc. -- are left to the local retailers. Among the company's 80 grocery chain clients are Foodtown, Lowe's Foods, and Roth's. Its largest client is ShopRite, which operates 200 stores across the northeast. MyWebGrocer.com charges retailers a transaction fee and monthly service fees for advertising and marketing. The company was founded in late by 1999 CEO Rich Tarrant Jr., the son of Richard Tarrant, the former chairman of IDX Systems.
