I understand that air space is needed to preserve chips, but for chocolate? That's silly.

I've never purchased chocolate from either of these companies so I've never known that the packages are mostly empty space. One can make an argument that the package label mentions the weight of its contents, but as was mentioned in the article, people buy things with their eyes and sometimes the visual package is misleading compared to the label.

Edgar replies: And Wayne, the legal argument that the net weight is on the package, has not been upheld in court. The law disallows nonfunctional empty space in an opaque package.
