Genesis Online signup - offer as shown. Called them and they threw in an extra 100 Power Shout hours and wouldn't discount the rates further. From what I have read online they don't really give out many Power shout hours "normally" during the year - maybe 20 hours or less?
I'm on piped gas too and the Genesis website doesn't allow me to mix a Standard user Gas Plan with a Low User Electricity Plan, which is the cheapest combo for me. Called them and they sorted this out. Also I wanted to lock in a 90c daily Low User Electricity rate before they raise it to 120c at some point in the future.
