Something I love about Costco is how they stock up locally with what's good there. You might not have black cod, but you have the flounder which we'd never see here. Same as they have (heart be still!) fish like opa at Costco Honolulu that I'll never see in Bellingham.
The cod was good, but what an interesting exercise fileting it was. Once you get the filet off, you realize that each has one big meaty side and one thin side, and that the thin side is full of bones that are impossible to remove with the needle nose pliers that work so well on most other fish. I ended up just cutting that side off, and rescuing the few bone free bits to thread on a skewer so as not to waste anything unneccessarily. The ratio of good meat to waste parts was about 1:1, so $8 a pound didn't end up being a bargain. Oh, and when I threw the parts out on the patio for the seagulls? NO interest. Zero. I thought seagulls would eat anything and everything from the sea. Ended up having to pick up the mess and hose down the patio.
My wine shopping and I have never had a problem. Just a perpetual race between the bankruptcy court and Hell.--Rogov
