We make a point of buying one each time we go to Costco, even if we don't need it for a meal when we get home -- mostly because I want the carcass to make broth with. We have big eaters here (young adults), so we don't get quite as many meals as you do. Indeed, if both young adults are home we get one meal: I eat half of one side of the breast, DH eats a leg, a wing, and the other half piece of breast, young adult #1 eats one side of the breast, and young adult #2 eats a leg and wing. At that point I can pick the carcass for soup meat, and make broth. But it's still worth it for $5. With young adult #1 away at college I can set aside one side of the breast, and share that with DH for one more meal, or shred it and stretch it into two more meals (yellow curry, chicken quesadilla, etc.)
