I mistakenly spent $10 on 2 sticks of butter the other day. After going home and trying it I understand why it's so expensive. It was so good! You can get it at Eataly in the Flatiron District. Highly recommended if you want to impress your dinner party guests. According to their website "It's so good that it can even be eaten on its own".
yeah, i was curious about some artisan sea salt butter from a vermont dairy and i'm now a converted man. excellent butter is definitely worth it, though i wouldn't cook or bake with it (pricey), best to use it sparingly when the flavor will be able to really come through (on bread, crackers, potatoes, steak, etc.)
