I bought some jumbo lumb at Marianos.
I don't know if it was blue crab.
The brand was chicken of the sea, and the containers were sealed clear plastic so you could see what was inside.
The ones I bought had a metal lid, like a soup lid that peeled off.
The quality was good and they made awesome crabcakes on NYE.
They also carried other types that were less $$ claw, and backfin ?
There were a total of maybe 4 other types of crabmeat available in the same type of container. All were refrigerated, not frozen.
