May be in a few years, we will be having a subject 'Grocerology', so as to teach everyone from early days to cope with the problems one can face while buying food.

It's weird to know that they've penned down strategies for shopping. I've never had any strategic shopping ever in my life. For grocery, not at all!

Also idk but may India doesn't require such strategic plannings for grocery shopping! I'm lucky, maybe!
