Just to add...
After Setzer sold his stores, he started Pic N Save which grew similarly and handled some grocery items.
Piggly Wiggly was controlled by the Lovett family after they sold their interest in Winn-Lovett to the Davis family for what became Winn Dixie. For many years, even though they had no stores here, Piggly Wiggly was HQ'd here.
There was another chain, Colonial Big Star, that was in this area. And, Banner Food Stores. Not sure, but at least one of these could have been a franchise-style operation.
In the mid 70's, Jacksonville hosted a joint venture between Skaggs drugs and Albertsons grocery stores called Skaggs Albertsons. After their partnership broke up, it was just Albertsons.
Of course, Food Lion and Harris Teeter have passed through town as well.
There was a 4 store grocery group called Premier that was mainly in the NW Quadrant.
We shouldn't forget some one-store operations like Mandarin Supermarket that served Mandarin long before any chains arrived. Today, a Publix store stands on this site.
Few know that Publix actually has come to Jax twice. The first time, in the early 1960's, they opened at Gateway shopping center. That failed and they didn't return until around 1971 with their first store at University Blvd. W and St. Augustine Road (now LA Fitness).
