This is extremely widespread, if not totally universal when it comes to really expensive items.
No-one ever seems to care or notice - I often unfold the paper so the price shows again, as it’s one of my pet peeves.
It does indicate both how blind Swedes are to the faults in their own country, and how passionately defensive they are though.
Edit: This doesn’t seem to me to be highly relevant to the general discussion on shrinkflation, but to avoid the very active downvotes I’ll post to imgur tomorrow evening (when back in town).
If you shop in stores that break the law you should take it up with the store manager, store owner, Stockholm's konsumentvägledare [0], or Konsumentverket [1]. They're violating the law [2]. I hope you had a nice vacation outside of Stockholm, no need to add an extra errand to your list when you're back in town.
