I have had packaged seaweed before, the little snack packs and enjoyed that tremendously. My friend accuses me of liking some off the wall food! I would love to find wherever you're shopping as the prices aren't the same here, and I dont' think I've ever seen seaweed in the local grocers. What I had, I purchased online at IHerb.
