Morrisons actually inherited a handful of Safeway Megastores which had ESELs way back in 2004. They didn't last long in the great purge of anything that resembled technological progress.Critique wrote: Sun 20 Aug, 2017 22.59 A couple of years after we discussed Sainsbury's testing them, and YEARS after we discussed on here the use of them in a Morrisons Local store, Tesco seem to be be the latest supermarket to be experimenting with e-ink price labels in one of their stores, as shown in this tweetfrom SirKen. Indeed, looking back they're the same ones that Sainsbury's tried out, which could even go red for items on promotion! They've came a long way from the originals, which much like the initial Kindles were quite dark, whereas these are very clear, even from a distance.
Sainsbury's ran a trial around the same time in that Cheshire concept store, removed a few years later.
Tesco previously trialled some sort of LED or LCD screen which filled the entire strip - I think that development all ceased around the time someone realised they were cooking the books and a load of execs were showed the door.
It is a very sensible bit of automation, I imagine it'll be standard fit out with the big 4 before too long.
