Clothes
Well, I go to Penneys for bits and bobs, you really can't beat them for value, and the kids clothes are brilliant.
Their clothes do seem to fall apart/shrink quicker in the wash, so if I need something a bit longer lasting I shop in Dunnes Stores or Dorothy Perkins. My staple work "uniform" is black trousers, tops and cardigans so it doesn't have to be expensive. Also, my local market is great for "seconds" designer jeans, so I get great value there, I recently picked up a pair of Levis and a pair of New Look jeans for €27 for the two.
A bit of a trick is to go into Penneys on the last day of the month, they seem to have more sales then. O'Connell Street always have more discounted clothes than the new Mary Street store, I still can't get my head around this!
Oh, and I always go shopping with cash in my wallet, I find that if it's gone, I can't buy anymore and stick to the budget, otherwise you don't feel the impact if you use the Laser card or Credit Card.
At least once a month we make a trip to Newry to get all our non-perishables, pasta, rice, tinned goods, juices, cosmetics and our clothes. The Primark store in the Buttercrane is the same as Penneys in Dublin and is a total mess, but there is even better value to be had there if you are prepared to dig around. New Look, Etam, Dorothy Perkins, the whole lot are there, and you'll be sick if you take a look at the Euro/Sterling price tags, I haven't bought from the english stores in the republic since
