During the beginning of all this everyone was freaking out about how we were going to be able to ship and store this magical elixir at -70F. They were adamant about it. People were worried about refrigeration shortages.
I'm sure it cost a significant lot more to ship something then store it at -70F.
What happened that we went from this getting shipped in temperature controlled shipping containers, to sitting on a truck in a cardboard box next to my Amazon order...
Maybe that was before they added the ethylene glycol (antifreeze).
Or after, if the subzero temps were for something else and they needed antifreeze to keep it from turning to ice
