Europe has had this for a decade.
Digital price tags on store shelves.
I have literally seen a price change (upwards of course) as I was reaching for a bag of cookies.
Someone knew I was the Cookie Monster.
I found a price on a herbicide Saturday online at the Lowe’s next to my home for $24.98. Under 30 minutes later, I was there and I grabbed two for my cart.
I got up to the self checkout and it rang up at $26.99. I showed the lady there what it was, then refreshed, and it gave the new number.
The lady said all on line prices can change.
I told her I show this as $24.99 at TSC, so I will drive there to get it.
I left and got them there.
