Check that you have the proper level of house insurance, I know that this is discussed in detail on another thread, which is worth having a look at. I am no expert, but it is worth making sure that the level of cover is right, and this could save you money.
As others have said, shop around. I notice that Dunnes, for example, are making a bit of an effort now on prices. I also find that Boots own brand products are generally very good, and good value.
