> On a related note: Lidl tried and failed to get a foothold here in Norway with similar tactics. It didn't work. Perhaps because our mainstream store chains are already so similar to Lidl, except our domestic chains offer actual name brand products and the Lidl stores didn't, and I think that's why they failed.
I don't think that sounds like the most likely reason. I have seen Lidl's arrival to Finland. And at least with respect to prices Norway and Finland are very similar, namely exorbitantly expensive if you compare to central Europe.
Also in Finland price competition did not use to be very fierce. They are only few players and it was an unwritten agreement that business is more comfortable to do without any price wars, consumers pay...
So when Lidl came there was massive pressure on suppliers not to sell to Lidl. If you sell to Lidl (with initially some 20-30 stores) you will not sell to us any longer (with many hundreds of stores). For several years Lidl had to ship nearly every product from central Europe. Which was not only expensive, but also were the products partly exotic to the consumers. For me as German living in Finland Lidl was better than the finest specialty shop, lots of products you could not buy anywhere else and very cheap. After a couple of years the supplier boycott started to fade away, consumer acceptance grew and my specialty shop was no longer :(
Could it have been a similar story in Norway?
Finland was also hit hard by a recession from 2008 - 2017. I understand Norway was doing much better these years and salaries are high. So the demand for low price options might have not been so wide-spread, making their market entry even more difficult.
