No, they aren't. I noticed that sign too! I buy them at Safeway...
I think it's about $6 for 18 eggs, and Safeway usually has them buy 1, get 1 free. Or you can just buy 1 18-pack at Costco for about $3 for regular eggs.
Organic, free range, etc, etc, etc is just way too expensive for me. I know it's better for you, better for the environment, but it's just not feasible for me.
Housing and food prices in Hawaii are kinda crazy, but we really do try to support our local businesses as much as we can.
