As of now, my local supermarkets still have price tags on the shelves. And if there's a higher price at the register when the item is scanned, they will honor the shelf price if you call it to their attention. The biggest supermarket now has e-ink shelf tags so I assume those are synced with their item database so that doesn't happen anymore.
