OK.

Not in the 5 state area.

Why I’ve never heard of them.

Eh? The map that came up directly for me, upon clicking the link, was for Kroger. But backing through the images, I found a map of Publix stores.

That map's worthless. It says they're not in Florida, but I know for a fact that they are all over Florida.

They're confined to the southeast. See their interactive map.
