Will you save? yes
Will it be enough for you to notice...not so sure, but the combination of doing everything should. We keep a lot of things unplugged at my house as well.
I don't do it as it's not feasible for us, but my uncle also flips the breaker on his hot water heater over night...again, I can't do this as I shower first thing in the morning....Just an extra tip if you haven't thought of it.
