These lids are re-usable, are they not? Once a jar is opened, the lid can be washed and put on another jar. Given that, I personally can't imagine ever needing 24 dozen of these lids. I have a small family, so don't think it likely that I would ever have 24 dozen jars of food on my shelves at one time. I do plan to get some of these though, just not quite so many.
