Thanks for helping me figure out how to book this. I couldn't get it to show on ITA so I wondered if it was valid. It looks like it might not be the best deal for a pure mileage run due to an apparent minimum stay and the codeshare, but it still looks like a great deal for anyone needing or wanting to get over to Dublin from the West Coast for well under $400.

Since you all found out how to book it, I guess I'll do a quick post on Deals just in case someone missed it.
