Well if you want to treat yourself, the place we get them does ship. They are fresh off their boats (the retail storefront and the boat docks are all in the same building) and you can't beat their prices. Hint, buy the mediums ($14/pound right now). You get the biggest bang for your buck. The larger you go the more you are paying for shell weight versus meat as the shell keeps getting thicker as they get bigger. I'll even post the recipe (if we already haven't) for Joe Stone Crabs mustard sauce that we got years and years ago.
Grimm Stone Crab- Fresh Florida Stone Crab Shipped
Craig bought 3 pounds yesterday and we have a little bit leftover, enough for an appy for 2 or a small batch of ravioli with red bell pepper sauce.
Shipping, unfortunately, will double your cost as they only ship air but if you buy a bunch (maybe go in with friends) they cost will go down per pound as the cost for air shipping is only $2 more for 10 pounds than for 5 pounds.
