I write to ask you to please help conserve energy. Many WalMarts leave all their presentation TVs on all night – this makes no sense. No one is watching them. you could turn off half of them, save millions of hours of energy, and be more “green”. I have been in some stores which make use of skylights in the daytime for light. This is a great first step. Please, please consider turning some of these TVs off. Thank you.
