I have read that once unfrozen, it lasts for 30 days while refrigerated at a reasonable temperature.

So why is the -70c an issue at all? It seems totally reasonable that we could just ship it at refrigerated temp and it would all be used up well before the 30 day expiration.

The only explanation I can think of is that the information I read was wrong and it won't keep that long after thawing.
