Unfortunately it looks like this deal is more of a rip off. Tails are substandard in size and seems most of the weight is in the claws. So these lobsters would not be considered prime choice and thus sold at a discount which is passed along as a special deal here. I wouldn't be surprised if there was some rounding up of weight such as 4-1/2 pounders are sold as 5 pounders, etc.
