Perhaps not as interesting as some others, but as a full-time domestic engineer, it is to me.
I would like to see sale information, new products, specials, and other stuff at my local food emporium(s). Frinstance, I was shopping today, and noticed that my preferred brand of a given product was now available: I had looked in vain for years and there it was. This could be the first week it was there, but how useful would it be to have a list of new products, seasonal produce and seafood, manager’s specials, that kind of thing.
Probably way down the list, especially with the demise of the delivered grocery services (HomeGrocer, WebVan). But I’d use it if it was there.
