in EU labels must show prices per kilogram of product, to make this kind of fuckery harder

Isn't this required in US stores now as well? Everywhere I go I see a $/oz next to the price.

Though my state doesn't have this law and I still see it at all stores. I very much rely on it, and it should be law.
