Perhaps a first step is a low cost dry ice shipping box with a super insulated
dry ice frozen compartment, a fan, and a fridge compartment. Without any
control, dry ice shipping is freeze-thaw, then not necessarily come to life.

My proposed shipper-frigerator would maintain a 4 deg C temperature for many days
of shipping. The size could be made to fit inside flat rate boxes
so they could be used when full of dry ice at a $13 rate,
then for dead-head return shipping of empty ice boxes
the under 13 oz first class parcel rate would be under $5.

An ice box version with a slightly more permanent exterior would do duty
in a lab and would work with water ice cubes and a drain bucket,
or with dry ice.
