You can get it in most supermarkets or offlicienses. It costs 120 euro, but I would recommend getting it in the duty free at the airport, where it can be picked up for about 75 euro, assuming your friend is travelling out of the eurozone. The 2003 is deffinately in the duty free, as I saw it last time.
I would also recommend Redbreast, Greenspot, Jameson Gold, Blackbush, Bushmills 16..., which can be picked up for much cheaper.
The Midleton VR tastes nothing like any of these, though. It's different to any Irish whiskey I've tasted. It's not a monster of a whiskey, but is just beautiful (in my opinoin, of course). The other Midleton VR vintages are not as good.
