I always assumed that any stores using these had them networked together. So the argument being that they don't have to pay someone to go around and update it and instead can just do it centrally? I think the Amazon stores do this, and I would assume that if anyone Amazon would set that up properly. I also thought I saw somewhere the idea that the displays let them tinker with the price more often instead of on a weekly basis when the flyers come out.
