Just to update an old thread- Avoid Marbledcrayfish.com
Ordered 5 Crayfish and shipped via the "cheeper 15 method" per recomendation of Mark. All but 2 Arrived Dead. No recourse as I did not ship overnight. He was rude despite the shipping being at his suggestion since we lived only 150 miles apart. Warning!!! Would not do buisness with again. In the end it cost me $65 for 2 Crayfish. Do yourself a favor and find another Dealer!
