yes, i save wing tips and also the thanksgiving turkey carcass; it's all useful for stock. in addition to the ingredients you listed, i also add whole peppercorn and parsley. it all goes into the slowcooker. as for the foodsaver, we owned one and used it only once. just gave it up recently to someone who hopefully puts it to more use. i simply measure my stock in one cup portions either in ziplocks lying flat in a container (container removed once frozen) or in tupperware. a couple of other items in the freezer pantry is homemade marinara and lasagna. it's only p and i, so we never finish up all the lasagna whenever i make it. it freezes nicely.
