This may be a dumb question, but how do grocery stores store the dry ice they intend to sell? This stuff has to be kept very cold to prevent it from sublimating. Do they just keep it in an insulated box with a vent and just accept that they will loose some of it?

This is what the stores near me do, yes (they're actually freezers, but certainly not ones that reach dry ice temperatures). I don't know if they have a separate storage location they use overnight while the store is closed, but I suspect not.
- Retric 3y agoYea it just vents. This might seem odd but it’s cheaper than maintaining a cryogenic cooling system. Very well insulated containers are cheap and heat gain only occurs along a surface where they’re storing a large volume. So losses per day end up being trivial when they’re only paying ~0.5$/pound and selling it for 3$/pound.
