I'd be surprised if Kielys of Limerick don't feel obliged to do their best to match whatever appears elsewhere...(?)
The annual Savins free-for-all might be worth checking, too — usually around the 6th January, but might be earlier this year given the way the holiday falls. They usually stick up a 'one only, first come first served' giantscreen at half-price or so.
The DID website is not particularly up-to-date, though - most prices say "Call for price".
Also, beware of the interest free "option" that DID, Harry Norman and co. offer. You can end up paying way more than you intend. I'm sure this has been covered to death elsewhere in AAM already.
I've toured a few shops and it seems they have all started their sales already. Also I quizzed the guy in one shop and told him it was cheaper somewhere else, (chancing my arm) he said it couldn't be as they are all reduced by the same amount everywhere.
Seems the distributers fix the prices and all the shops follow.
