Has anyone been in a store that uses these digital price tags yet? They are like the display on a Kindle or Boogie Board. They only use battery power to update or change the display. Otherwise, they just sit there showing the last thing they were programmed to. It's a big advantage, when they need to change the price for sales, or hang a different product, or completely rearrange the store, they can just execute a command that flashes them all to the updated info. Pretty cool setup.
