Lobsters $4.99/lb at ShopRite in Bayville
The South Jersey Shoprite ad 12/3012 - 01/05/12 does not show the whole lobsters being on sale however I believe they were in the $5.99 lb range all summer/fall with an occasional $4.99 lb.
I bought a case of frozen cold water tails @ Restaurant Depot in November for $14.99 lb. I wrapped them in butcher paper to cover the sharp shells and then vacuum sealed them in batches of 2. They have great flavor & texture & the convenience of having them sitting in the freezer next to aged NY strip steaks is great.
