Absolutely. Packaged stock is mere salty water by comparison.
For me and, I'm sure, for erika, making stock from scratch isn't a new habit acquired since the economy went south. I've been doing it all my cooking life (which began at age 7, when I made a blueberry cake with streusel topping). Of course, my mother grew up during the first Great Depression, so I learned such frugality at her knee.
