A series of events, including free cake, will take place through July 21. One customer will win a $100,000 grand prize to promote the new format.

"We've spent the last several years improving our stores, our merchandising and our service," said Chairman, CEO and President Peter Lynch, in an announcement. "Now, Winn-Dixie customers in the Jacksonville area, no matter where they shop, will find a fresh and local shopping experience, with enhanced customer service, every time they visit us."

The units are located in North Florida and South Georgia, part of a companywide remodeling plan to upgrade 75 stores annually in the Southeast. The redesign of each unit was tailored to the individual market, but all feature a new color palette and signage, and fresh, local merchandise. Other elements may include: expanded produce departments, a greater selection of organic and natural goods, wood-burning rotisseries, a custom sandwich shop and hot food bars.
