It will be shipped in a dry shipper. Basicly a liquid nitrogen tank wihtout the liquid. A dry shipper holds a charge for 7-10 days. It shouldn;t be opened until you're ready to move the semen to a liquid-liquid nitrogen tank.
I usually move it to my tank the same day it hits my porch. Then UPS is usually back the next day to get the shipper.
They will not ship over a weekend, usually. Most shipments are made early in the week so the shipper doesn't sit around somewhere other than your porch.
