Well! Today is that day.
Last month's bill: $71.95
This month's bill: $44.11
We saved that money by simply turning off our surge protectors (and the stuff plugged into them like the modem) at night, making sure we didnt use lights when we didnt need to and turned off lights when we left the room, unplugged cell phone chargers during the day and lowered the temp on our water heater.
And almost $30 richer because of it.
