Sealing Electrical Outlets

Today I decided to actually put the insulating gaskets in my electrical outlets. This is a very cheap and quick/easy way to save a couple pennies. Total cost a couple dollars (free to me, as my son had brought these home from school years ago), projected saving 0.25$ per exterior wall outlet/per year. I installed 11, so that was 0.22$ per month.
