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.
In Europe it’s required by law for most items. And it’s the only price I look at when I buy stuff.
One annoyance is when the unit is different for items of the same type.
In austria you usually get a per 100g price info
EDIT: when dealing with liquid you get a per 1L tag
