There is a good hardware on Capel Street in Dublin but for the life of me I can't think of the name of it - try google, you should get it there or at least they can point you in the right direction.
Maybe thats what they say but for years everyone I know has said that store is way too expensive so even if they have it I wouldnt rush into a purchase with them . One example is I recently went in to price a special bulb and it was something like 7 or 8 euro there and 2.99 in the Roches Stores in Henry Street. No contest for a 10 minute walk across the happeny bridge.
