Buy beef liver instead of calves' liver. It's a better buy for the money. Buy whole chickens. If you want only breasts, save the dark quarters, freezing for later use. Buying breasts alone is very expensive.
Turkey offers better value than chicken.
Larger turkeys are more economical than smaller ones because they have a higher proportion of meat to bone. Freeze leftover turkey for use in sandwiches and casseroles later. Chicken livers are good broiled, folded into omelets, or chopped and made into a spread. Smelts are usually much less expensive than salmon, halibut or sole. Raise herbs as house plants.
