I have narrowed it down to two places to get them.
Big chain store $4.95 lbs skin off
Local Hispanic market $2.89 skin on.
I am probably going with the local guys just because I would rather give them my money but I was courious about the weight loss of the skin.
I'm on the gulf coast and I know you can lose 50% on crawfish and shrimp after peeling but I wouldn't think it would be as much on meat
