Winn-Dixie has unveiled plans to convert some of its Atlanta stores to SaveRite Grocery Warehouses . The move aims to close a gap in the market created by last year's withdrawal of Cub Foods . The new stores will offer a more limited range of goods than the group's conventional supermarkets, but will boast lower prices. Conversion to the new format is being piloted in two new stores, with two more expected to switch over today and at least five more by 10 February.
