In the US it is widely available dried along with several others, but is quite expensive. It sounds like Maine Coast Sea Vegetables can't harvest enough to keep up with demand (although flakes or powder are available in bulk). Nori seems like the most popular seaweed in the US, though. I tried a bunch of varieties years ago and found dulse to be my favorite snack seaweed both from the flavor (I like it better than nori) and because it is easy to eat out of the bag while others (besides nori) are quite stiff if you try that.
