> 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…
Without knowing it exactly I have an idea that Norway might be a harder nut to crack because it is outside the EU and some rules don't apply there. I seem to remember something like a butter (?) crisis over there some time ago. That could never happen in a country that has fluent trade with its neighbors.
Norway is a member of the common market, it is said to be the most integrated non-member. Aldi/Lidl seem to be successful in Australia, USA, and Switzerland so I don't think EU membership is a requirement for their business model to succeed. Without being an expert in the field, I'd say it's more important to find the right balance between the aggressive company model and some local practices you better do not attack. Some local managements seem to be better to find the right middle ground than others. As also mentioned in the article Walmart failed in Germany. But Mc Donald's or Ikea haven't, so it can't be generally impossible in Germany.
However, being a member of the EU inner market does not apply for agriculture in the case of Norway. I guess this means if you have are sourcing frozen french fries you can get them on the EU market, but potatoes you need to source locally or pay potential customs. But I am not sure how the border line between agriculture and everything else belonging to the common market is actually defined. Nor do I know how relevant customs on agriculture are.

France had a butter crisis in 2017. Your search engine will bring up many articles. But France is in the common EU agriculture market and France is in the Euro. So I don't think your argument really holds. Whether Norway had a any butter crisis is beyond my knowledge.
