I lived close to a small Aldi store when I was studying in Germany and shopped there for years - it was much cheaper than any place else and I don't know how I would have gotten by without it. I now shop regularly in two Aldis in Dublin. Both of them are a little smaller than your average supermarket and I pay less than half of what I'd pay in Tesco, for example (and Tesco has been forced to reduce its prices across the board because of the competition of Aldi and Lidl). A largish-sized Lidl store opened up last week across the road from one of the Aldis, and there is expected to be fierce competition between the two.
