That's pretty interesting. Were there different flavors in each country as well? My friend brought me some paprika pringles from iceland and they were delicious. So good that we ordered them online but the online versions shipped terribly and were delivered as pringles dust. I used it to bread chicken which still was pretty good. But if you are in iceland get the paprika pringles!
That is mostly because the same brand made for Eastern europe tastes like shit compared to the stuff for western. Worst offenders are nutella and coca cola. but there are many others.
I have tested this in Denmark, Poland, Cyprus, Ireland and Germany.
