Walgreens probably still does those late night stickers for price changes, if anything needs to be digitized it would be that. For the benefit of the employees that have to do that painful mess of a price change constantly. Next time you visit a Walgreens or similar store and see tags everywhere just consider how much waste there is to do that every week, sometimes with the same prices just a new colored sticker.

We've had digitized (eInk, LCD) price tags for well over a decade now. They just haven't seemed to take off anywhere except for Kohls (at least in my area).

I noted in an earlier comment that I recently saw virtually complete usage of e-ink price tags at Best Buy (some fairly large - like tablet display size). But Kohls is where I first encountered them in the wild - they seem to be one of the earlier adopters.
