I have been getting stuff in Lidl and Aldi since they came to ireland, had used them in other countries before then and had also used Hofer in Austria (same as Aldi). They don't tend to have the same negative reputation in these countries as the competition has managed to give them here. Despite all the evidence to the contrary, Lidl and Aldi have a reputation as some kind of poor people's supply stores, and a lot of shoppers are still reluctant to admit that they shop in them.
In our house we wouldn't go anywhere else for milk, washing powders, Brioche (aldi), bottled waters, potatoes, most veg, cheeses, ham, frozen pizzas, luxury ice cream, and a lot of other products. However, has anyone noticed the huge difference between Lidl prices in Ireland and Lidl prices in Spain, Gemany etc? If they can afford to sell at these low prices in those markets, they must be making an absolute killing in Ireland.
For example, a six pack of small bottles of drinking water is about 1.70 euro in Lidl in Ireland. In Spain the same product is less than a euro. Similar differences in many other products.
