Are many egg cartons actually labeled as "caged" around you? Where I am its either advertised as cage-free or its unlabeled. Its not like the options are "tiny torture chambers": $2.99, "unclean hellscape": $3.99, "rainbows and sunshine": $4.99. Its also hard to tell what these things mean, because "cage-free" can still be a pretty terrible existence for the birds as well.

But I do agree though, if there's a seemingly similar product with a much cheaper price tag a ton of people (myself included) will often reach for the cheaper product.
