Also I'm not quite sure about the grammar of "Aldi's"
:)
It'd be amazing to see this data mapped across time, as it'd be a relatively good indicator of grocery inflation.
Close at the border we have a lot of shops where people from Denmark (and even Norway and Sweden) travel to to go shopping, because it is so much cheaper here. But thinking about it, I have never seen/overheard Danes in an Aldi - and I wonder why?
It may also be partly due to Aldi reluctance to carry brands beyond their own. For some items Danes don't care, but if you then can't get the brand name cereal or ketchup, then you have to go somewhere else anyway. The Danish supermarket space is insanely competitive, in regards to price, so Aldi just didn't have much of an advantage over local discount stores anyway, at least not enough that you'd bother splitting your shopping between two stores.
I believe they lost €125m+ per year in the final years, loses that need to be covered by Aldi Nord in Germany. In the end they just didn't want to keep losing money. REMA1000, from Norway, bought a large number of the stores. Not sure why, they look nothing like REMAs own stores, and in some places they are literally across the street from an existing store.
But I've heard that it has not the whole collection of items available as the physical stores.
