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.
Unless it’s something like fabric softener. Then some brands might use price per 100 ml while others use price per wash.
Metric system still rules though.
