Public transport I am based in Timaru and although it is a small town, it is cheaper than Dublin/Ireland and most town in Germany, even for short rides over there.
Good chocolate is cheaper too! (whether thats a good thing is debatable) and I have to agree on wine, but only compared to Ireland. Germany has its own great selection at much lower prices. The same applies to toilet paper.
We didn't have to buy one over here but while shopping whiteware we noticed that TVs are quite cheap compared to Ireland/Germany.
