Aldi are fab. I suppose a lot of their stuff is home brand, but they have a lot of common brand stuff too. But they only stock the one brand of any item and sell it quite cheap. Their pannetone rocks at Xmas time, and every week they have a themed special eg. tools, wooden kids toys or clothes, German food for Oktoberfest, or homewares.
The stores are pretty simple, and the queues can be tiresomely long. But a lot of their stuff is such good value.
