My order of 40 (replacement for previous DOA) fiddler crabs and 25 common shore shrimp arrived at 9:50 am. I had this one shipped overnight due to freezing temps. Everything was very very cold. I lost 3 fiddlers but all shrimp arrived alive. I requested an insulated box w/heat pack, got the insulated box but no heat pack, don't think it would have made big difference. Overnight shipping was expensive but necessary. Paul Sachs is a good guy to do business with. I am happy.
