I’ve already seen this in essentially every supermarket ever, usually per ounce. Sure, you have to have some vague intuition about what that is relative to the product, but you can still make standardized comparisons across, say, different kinds of chips, very easily.

It’d be nice to include taxes, I agree.
Including taxes doesn’t really matter for that measure.
The bigger issue is that they’re unreliable. They’re often not updated if there’s a sale, for instance.
