As the picture shows, most (all??) grocery stores will show the price per ounce on the item’s price tag.
It’s usually on sales tags too.
I was FAR too old before I realized this and it’s made price comparisons in-store much easier.
Note: Not my photo. Just generic photo from google.
In my country its a law that the "price per weight" has to be on the tag. It may vary which unit they are using but with the metric system its just a matter of moving the comma.
