Holaaa Eva! Happy to see that you enjoyed your trip to my homeland again hehe :) Yes, here all supermarkets and hypermarkets are open every day, including Sundays. I remember it happened to us many times when we lived in Poland that we went to Biedronka to do some grocery shopping only to realize that it was Sunday and it was closed :D
