One might think that shipping frozen whole is just great. I mean, no work, stick 'em in bag, freeze them and stick them in the mail.
As far as I am concerned it is a pain in the rear. I much prefer to skin, and salt. Any loss in shipping is on the shipper and you are always worried about a hiccup that delays the shipment.
This very same customer ordered 6 frozen whole a few years ago and they all were lost. Cause was a delay due to the closing of a regional sorting facility. Not my fault but insurance will not cover loss due to delays in shipping. But you have to cater to the customers' requests.
