Cut the a/C bill by increasing the temp to 80 degree in summer and winter keep it to 64 degrees.
Cut the food bill feed them with half of the meal size (2 meals with existing one meal) and two times a day and not three times a day. Take one meal for poor people in our neighborhood. No cable TV at all. Let them starve and think of God and they may not never comeback because of hardship. Let them work some yard work. If they no meal for two days.
