Thanks for stereotyping. I have and am still paying rent for all my life and the rest of it.

“Should” is meant here for a better/good way do do things. If it is not possible, a “should” just is not applyable, it is a “should” after all.

Maybe this is a language/cultural/mental perspective misunderstanding.

What? How can my comment possibly be voted down?

You should shop by ingrediends and ecological reasons. That’s sadly not represented by $/g.

The heavier product with the better “bang for the buck” is usually the one with the poorest quality and lots of sugar/additives/flavours/etc.

Discounter products like “Great Value” can easily have a better quality than stuff produced by “Kraft” and other Unilever/Nestle/etc. products.

Checking the ingredients list and the nutrition table should be a natural first instinct when grabbing something off the shelf.
