I usually buy http://www.realsalt.com/
Ever since I did the disolve in a glass of water test between table salt and real salt, I won't use table/refined salt. My friend noticed a difference in the flavor immediately (although I didn't). She said it's sweeter. I read that refined salt is heated over 300 degrees and it becomes altered to a point that it's acidifing in the body, but realsalt is alkalizing. Don't know if that is all true, but, still, since the glass of water test I'm sold.
