It's interesting to know that products on Amazon might not be the lowest price, or always close. I thought there was more manual price research and setting, like Walmart.

Walmart can't change their prices as fast; humans have to re-label things. For now.

Brick and mortar retailers can use radio-controlled e-ink shelf price tags for minute by minute price changes.[1] This hasn't really caught on yet, but the technology is ready.

My mother used to be a scan coordinator at a grocery store. We have been talking about this eventually happening for over a decade. Although based on her experience, the infrastructure for even letting her know what pricing should be requires a major IT overhaul as well.

How does that even work? You pick up the product and the price changes by the time you go pay for it? Who would like that?

I saw e-ink shelf tags deployed throughout the store at a Whole Foods Market in Sugar Land, Texas.

In Ohio at least, Kohl's has had e-ink shelf tags for the past few years.
