Can't really go wrong with that, even if you're not a fan of Miller. it's the cheapest slab price I've seen. Not sure if all branches are doing it, I know the Nutgrove branch are doing it though.
Edit: before anyone asks, they are the 500ml cans ;-)
Guessing there must be a massive batch of Miller that goes off in January so, considering Tesco are doing them cheaply as well.....Happy days!
Sorry, think they're Dublin only.
