Publix is the most prevalent grocery store you’ll find in the area. Their stores are all clean, bright and spacious and have a good variety of food supplies.
A few years ago they added sections of organic foods throughout the store that they call Greenwise which give you the option of getting some organic vegetables and packaged foods in a regular grocery store.
You can visit the Publix website to see more about them and here is a map to show their locations in Dunedin and the surrounding areas.
