Just got back from a week in Ireland. They're paying close to $10/gal over there once you do the conversion.

On the plus side, if you live anywhere with a Giant Eagle in the area you can get their Fuel Perks. Buy $50 in food and get $0.20/gal off your next fill-up at their stations. Since I wait to fill up until after the gas light comes on, I'm saving a minimum of $3.40/tank. And since you can stack them, I'm normally getting $0.40-$0.60/gal off.
