I see it in supermarkets, often kept by the customer service counter.

I've seen several places requiring ID to purchase dry-ice to avoid youngsters making soda-bottle bombs with it.

It's dangerous enough (suffocation, freezing) that there are plenty of reasons to require an age minimum. I don't think I've seen dry-ice in supermarkets since COVID started, but I haven't been looking much either.

Never disappeared around here. A lot of people rely on it to get their frozen stuff home without thawing out. So it's more available in rural places where people will have a long drive home.

Ahhh, that makes a ton more sense now. As one of the aforementioned soda-bottle-bomb-making-youngsters, I had no idea what people's legitimate uses for it were outside of party tricks.

I buy it on camping trips. It has a major benefit of not getting your stuff wet as it melts.

All of the stores in my area require you to be 18 and produce ID to prove it, yes.
