Thanks for the link to this thread Beernut.
The only other store I found Celebration stout is superquinn and they were €5.99 per bottle so I will be definitely picking up a few more cases. It was nice to see O'Haras getting some well deserved exposure on telly last week with Oz and James drink to Britain programme as they are one of my favourite Irish brewers, along with Galway Hooker and the Porterhouse.
