Every one of the posts I looked at priced in Euros looked like they were significantly more expensive than any shopping trip I ever made at SuperKing or Ranch 99 (in Los Angeles no less). I then went and sorted by top posts for the year and the only post that looks similar to the prices I actually pay was from a shopping trip in Algeria. Only a few posts of people paying €4 for a bunch of pastries and breads are impressive, the rest is just overpriced. That subreddit is not a reliable source of data or even anecdata.
