> Costco will sell you high quality cod and chicken at ~$10/lb (probably less in store) and steak around $20/lb.

Not sure where you're shopping or how much cod costs, but chicken is more like $3/lb ($2.50 on sale, and it can be frozen - and yes whole chicken is cheaper and more flavorful, but you get less protein per pound and it's just easier to compare) for boneless skinless chicken breasts and $5-10/lb for various cuts of steak around here, which makes it much more affordable.
