I remember seeing this for sale on BOC's website when looking for CO2 a while back (https://www.boc.co.nz/shop/en/nz/stench-gas https://www.boc.co.nz/shop/en/nz/stench-gas). I briefly considered buying some for nefarious purposes, but I think I figured that they probably wouldn't just sell it to any random person.
