You would need to send the product "overnight shipping" and use a specialized shipping container with dry ice (C02). That is where a LOT of the expense comes in. And then there is always the liability insurance issue if anyone gets sick if they do not re-heat it properly. The quality could suffer as well.
My sister sent some salmon, from AK, to me once this way. It arrived still frozen. But it cost her A LOT to send it and that was 15 years ago.
Do I smell SMOKE?????
