So some general advice pleeeassse would be so very appreciated

1. Ok so we have managed to cut down our phone bills, but the electricity and gas bills seem to be really slugging us. Which providers are the cheapest - anyone got some great deals out there they can tell me about?
2. We live in a city so we buy fruit and vege from the supermarket- farmers markets are not possible to go to on the weekend- so what have you all done to cut the cost of groceries?
We started having kangaroo mince alot more rather than other meat (its cheaper and seems more meat for your $), stopped buying bread (as we eat non-wheat bread and it is $), have looked into natural cleaning products like bicarb instead of commercial cleaning products, trying to cook at home rather than eating out, ummmm etc
3. Any other tips for cutting costs you have at all
