jings they can also sell at such low prices because they cover Europe, not just the UK. 15 years ago I did all of our shopping at Lidl, as it was right near my son's school, and our german exchange student was astonished to see that we shopped in the same supermarket as her mother.
We now have Lidl nearby ( by which I also mean 5 miles away, as are Aldi, Teco is even further, and Sainsbury) and I am so pleased - as the Lidl is very close to Sainsbury, it means I can go to Lidl and then top up from Sainsbury. I shan't desert Aldi, though. They had ostrich steaks last week!
