My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

Imagine getting 14 meals out of a single cooked chicken! It's my biggest food saving and this is how I do it.

Buy a whole chicken (on special of course)! Get a large pot. Place chicken in it and add chunky chopped carrot, onion, celery and mixed herbs (I grow my own so save more money here)!

Boil until the meat is starting to fall off the bone (I have a wood heater so I cook on that, saving gas in winter) Take the meat and vegetables out, reserving the liquid. Serve some of the meat and all the vegetables with mashed potato and white sauce.

With leftover meat, make up some chicken sandwiches and freeze them for quick lunches. Use the rest in curries or whatever other suitable recipes you have.

Back to the liquid. Add a little more water, chop up whatever soup vegetables you have or add lots of lentils, a dash of paprika and salt and slowly simmer to make a few meals of wonderful thick soup. This way, I feed two of us 14 meals out of the one chicken! Not only is it cheap, it is good for you and has helped the purse strings through many tight times over the years.

At 12 years old, my daughter is already helping our family save money on snacks using her Simple Savings skills! With five children in the house, we do a big shop just once a month and are careful to make our food and treats last until the next shop. Recently we were nearing the end of the month and getting low on food. I arrived home one day to find my daughter baking biscuits. 'They're Doos!' she told me. 'You always said if there was nothing in the cupboard, we had to make do, so I made Doos!'

The name has stuck in our house and now whenever we have 'nothing' in the house for lunch boxes, snacks or afternoon tea, she just makes a batch of 'Doos' using whatever she can find in the pantry to 'make do' with. She is proving to be very inventive with her recipes and is turning out to be a real baker. She'll turn out simple but delicious treats such as honey joys, choc chip biscuits, Anzac biscuits, pikelets and pancakes in no time at all! She really has shown that you can make something from almost anything in the pantry and would be wonderful at the $21 Challenge! Here is the recipe for her latest creation, called 'Sort of Scones!'

1 cup oats
1 cup self raising flour
1/2 cup sugar
125g butter
1 egg
1/4 cup milk

Mix all ingredients together, then roll into balls and place on a greased baking tray. Bake in a moderate oven (around 180C) for 10 minutes.

I couldn't be prouder of my daughter's efforts to help us save money and keep everyone well fed. Whenever we think our parenting has a lot to be desired, it's moments like this which prove we have to be doing something right - good things do rub off too!

My mother is chronically ill and disabled. She suffers from a rare type of auto-immune disease, called lupus, and is therefore allergic to most chemicals. This made cleaning difficult because she was allergic to most cleaning products, or those she wasn't allergic to were too expensive to buy on my carer's pension. Because Mum's disease is an auto-immune disease, I have to keep our house hospital-grade clean.

So I have come up with a fantastic recipe, and my house is spotless, smells great and is fresh and clean. The solution cleans and polishes everything, including windows. I have never seen glass and stainless steel taps look so clean.

This solution also lasts forever. Household cleaner used to cost me $80 per month, but now I buy detergent every three months, vinegar once a year at $1.50, washing soda every 18 months at $0.98c and eucalyptus oil once every eight months at $3.50 - a saving of $880 a year minus $20 for the few items I do buy. In total I've saved around $2640 over three years.

Household Cleaner

1 litre water
200ml vinegar
40ml detergent
40ml eucalyptus oil
2 dessertspoons of washing soda

Mix all ingredients together, and it's ready to use. Use 60ml of solution in warm water to wash your floors. Fill a spray bottle and use it to clean your table, benches and bathroom.

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.

I can make hundreds of litres of liquid plant food from just $12 worth of Dynamic Lifter pellets! This will buy a 10kg bag. Just add around four handfuls of pellets to a nine litre bucket of water and let steep for a couple of days, mixing occasionally. When you have a nice 'tea', pour a couple of litres of the liquid, into a nine litre watering can, top up with water and give your garden a drink. Repeat until all the 'tea' is gone, then add more water to the residual at the bottom of the bucket and repeat this process. As the mixture gets weaker, you can use on seedlings, vegetables and more delicate plants such as azaleas and gardenias. The 'weak' mixture can be used as a health tonic or sprayed directly onto the foliage of plants (remember not to spray if the weather is over 20 degrees Celsius, as this will burn the foliage). Once you get to the real weak stuff, simply pour the residual under a tree and water in well.

You can also make hundreds of litres of liquid fertiliser from a 10kg bag of Blood and Bone pellets at an initial cost of approxiamtely $1.20 per kilo. Compared to a litre bottle of liquid plant food (such as Seasol) which costs about $10 and will make just over 300 nine litre buckets (going on the manufacturer's average of 30ml per bucket), your bag will make many hundreds of buckets of first grade solution followed by many more second and third grade 'weak' solutions which are ideal for foliar feeding. A huge saving, which will give you enough fertiliser to last you a whole year or more!

Instead of buying Christmas presents this year, I asked my parents to write a 'book' for their grandsons. My boys love listening to bedtime stories so I thought this would be a great way for them to learn more about their grandparents and what they did when they were younger.

At first, my parents didn’t know what to write about, so we went through old photographs, scanned them into the computer and they wrote about what was happening in the pictures. We didn’t just use the usual photos like wedding pictures, but chose lots of candid shots and even photographs of places that evoked memories for my parents.

In the process of putting these books together, I learned things about my parents that I didn’t know and it made me realise that the 'book' would also be a perfect Christmas present for my brother and his family. So, for the cost of a few sheets of paper and some printer ink, I have an inexpensive gift that is priceless!

I pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!

I have read heaps about menu planning but found it all just so overwhelming. Choosing a menu for a whole month seemed like a lot of hard work but I have found a way to help even the most disorganised person.

Starting on the first day of a new month, and using a calendar or diary, write down what you have for dinner each night of the month. You will soon see what meals you eat on a regular basis. You can then transfer this information to the next month in your calendar or diary, and there is your monthly menu plan!
