Don't know why I've never done this calculation before.

I made stock this afternoon and, as usual, removed the breast from the chicken before tossing the rest in the stock pot. Today, on a whim, I weighed the breast and then looked up the price of boneless chicken breast on Coop's website. I was amused to see that the chicken breast by itself costs as much as the whole bird. So if you're willing to do 5 minutes of work to remove the breasts from the carcass, you get the rest for free. :-)
