I use a simple principle every day, which helps me save money in all areas of my life. I try to reduce my use or consumption of what I normally do by 10%. The rewards are enormous. For example, if you spend $200 a week on groceries, try reducing it by $20 over 52 weeks and straight away you have $1040 extra in your pocket. You and your family won't even notice the difference, as it equates to less than $3.00 a day!

If you apply this principle to all areas of your life - petrol, electricity, phone calls and so on, the savings are huge even though the sacrifice is not even felt. It not only saves money but also the planet by reducing your overall consumption. Once I achieve this 10% reduction, I do it all over again! Every quarter after the electricity bill comes in, I then set myself the 10% goal anew to keep myself on track and to challenge myself to reduce further. This means the $180 grocery bill then reduces by a further $18 a week and so it goes on. I have done this only to a point where it is comfortable and achievable. Because it is baby steps it is easy and fun and not painful! We have saved hundreds, if not thousands, in the last year or two and are not feeling so pressured by the mortgage rate rises. Best of all is that we haven't noticed any difference to our lifestyle.

I am saving around $100 a month on my grocery bills, thanks to a few simple changes to our family meals. I wanted to reduce our food bill and after some thought came up with the idea of making two nights per week a '$2 Dinner Night'. For example, one night we will have something like toasted baked bean sandwiches or stuffed baked potatoes; the other I use up all the leftover vegetables in the fridge to make a self-crusting quiche. This reduces the amount of food we waste and the kids love it. Even the simplest meals can be delicious and filling and the savings we are making from our twice-weekly $2 dinners are well worth it!

Making our own cleaners has saved us a fortune over the years and we have saved the environment a little too. '1001 Greener Household Hints' by John Schluter is full of simple household cleaning ideas and we went straight out and bought some five litre bottles, spray bottles and some of the suggested basic cleaning ingredients. The following instructions are from the book:

Air freshener: Mix one teaspoon of bicarbonate of soda with one tablespoon of white vinegar. Add two cups of water. Store the mixture in a pump spray bottle. Add scented oils for fragrance.

Spray and wipe cleaner: Mix two tablespoons of cloudy ammonia, a half cup of white vinegar, two tablespoons of washing-up detergent and four litres of warm water. We stored this in large labelled bottles and used in spray bottles as needed.

Bathroom disinfectant liquid: Dissolve 12 drops of eucalyptus oil in 1ml of methylated spirits and then add eight cups of warm water. We used this in spray bottles also.

We paid $5.00 for the book but have saved hundreds in the years since we began making our own cleaning products.

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

I leave for work at 7.30am and get home at 6.30pm, but I still need to prepare dinner for my husband who starts night shift at 5pm. If I turn on my slow cooker at 7.30am, the food is sometimes overdone by the time he gets up at 3.30pm.

To solve this problem, I have purchased a cheap plug-in timer, just like the one people use to turn on their lights when they go on holiday. My cooker now comes on during the day and dinner is perfectly cooked by 3.30pm! This saves on power because the slow cooker is not turned on all day.

Last Christmas, instead of buying everyone gifts, I bought some small gift boxes for $2.00 each at cheap stores and baked mini puddings and mini rum balls (I made heaps from one recipe), which I put in the boxes. I then tied them with a length of curling ribbon to make them look attractive. Everyone loved the goodies inside, and the maximum cost was $20 for at least six boxes.

I will definitely be doing this again this year. It will probably become a tradition - and why not?

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!

I grow most of our vegetables to eat healthy and save money. I save all scraps to compost and I wanted a tumble composter. They turn lawn clippings and scraps into compost in 14 to 21 days. The composter is priced at $410. I bought a 240 litre plastic drum (cherry bin) from the local trash and treasure market for $5.00. My husband drilled holes in the lid. It doesn't have a frame but I roll it on the lawn for five rotations once a day and I make compost in 21 days. It isn't hard to roll but I can't empty it into a wheel barrow (I'm only five feet tall) so I spread a sheet of plastic on the lawn and tip it out onto that. The compost is fantastic.

No more dashing to the shops to grab something for dinner when the cupboards are bare! I have discovered a great website to help make the best use of the food you already have in your fridge and pantry cupboard. It is (www.cookingbynumbers.com)

It gives you a list of ingredients and you tick what foodstuffs you have at home on the list, then it comes up with a range of recipes using those ingredients. It is amazing just how much you can make with what is already available to you! It saves on wastage and on buying extra ingredients.
