By "sold" we presume you mean "solid". Solid carbon dioxide used to be called "dry ice". It could be purchased in some beverage stores and supply houses. Once packed some samples in dry ice for transport from U of MN to Case in Cleveland. In a cooler the dry ice lasted for days. And, yes, the CO2 will displace O2. Breathing hazard, yessiree Bob.

Guess she TORPEDOED your concerns. (insert string of laughing emoji here).
There have been a couple of lawsuits over grocery stores selling sold carbon dioxide to kids most involving (deliberately) closed containers. You won't find them on Google searches since most are settled out of court.
In that last case I would love to see followup to that story; based on a personal experience with a dry ice chest, I find it difficult to believe two people would get into a car full of CO2 and not feel immediate burning of the mucosa and eyes that would alert them to the hazard.

A few years ago I was checking out at a grocery store. The store had a helium cylinder sitting unrestrained near the checkout stands for the purpose of balloon filling. I commented to the clerk that the tank should be chained up (double chained here in California earthquake country). Her reply was "oh, nobody will steal it".
I was collecting low temperature x-ray diffraction data on B6H10. The liquid N2 tank was running perilously low, normal delivery was several hours away. I took the city bus to the liquid N2 plant a couple of miles away and returned with a steaming 2-liter Dewar to save the run.
