From your other post, I see that you are staying at the Hampton.
Accoding to the map, near Ron Jon's store which is within walking distance there is a Winn Dixie which is a supermarket. I'm not sure how much "high" powered stuff they sell, but wine and beer.
Just south of you is the Publix, again a supermarket. It doen't look to far, but I never walked that direction to see. I believe it is about .5 miles south according to the map.
A bit south of that is ABC Fine Wines & Spirit. It looks to be about 1 1/4 to 1 1/2 mile south of the Hampton.
Now, this was taken from dave's map site and I'm not sure if anything has changed.
