I know this sounds like a very 1st world issue and “entitled American” question. But do any of you know if the grocery stores or gas stations in Poland sell bagged ice? We are wanting to take a small insulated bag for keeping things cold in?
I have been to Poland twice (2015 and 2022).
Unfortunately, I cannot answer your question about bagged ice. However, I noticed that Poland has everything for sale on the road that the US does. My guess is that bagged ice is available.
You may have already seen this on the Tripadvisor forum from seven years ago.
You can also try sending private messages to the locals who answered for more recent updaes.
Yes, you can buy bagged ice, maybe not in the first grocery you'll see but in the second or third one. Look for "Żabka" they should have it.
