Thanks everyone for all the great advice. Def some things I will be taking up.

We are pretty good. We don't have a dryer, so that is one fairly big running cost that I don't have. I am now unplugging everything at the wall, and have just done my first week of meal planning. I went to the shops and didn't impulse buy!! I have started turning off the TV or radio while on the comp instead of leaving it on as background noise. Nelle as great as home delivery sound, it is not an option as I live in a town that has a very small Coles and they do not offer the service.
