I know you said about cross border shipments, but Halftimebeverage.com have the O'Haras range, and its available in Vermont i remember seeing it there, just down the road from you NOT..
I think you could email the breweries maybe, then again isn't Craft beer = Craft beer for that very reason, thats its not mass produced and widely available..
Franciscan Well in Cork City is one of my favourite Irish Craft Brewers, but only draught.
