Yes I have, I think thats the best fare alright but just wanted to make sure it's not just the best fare at the moment and they won't change in a few months. I used that ITA software site and found a much better fare but it's not possible to book directly with them and the fare is not the same on the airlines websites for the same dates and times, I'm not sure if that's the norm with that site or not. Anyway for anyone wondering gohop.ie seemed to have the best fare being a little bit cheaper than the airline themselves.
