I have finally convinced my three daughters that eating a healthy lunch, including sandwiches with salad, is not only good for them but tastes great too. However, soon after changing their lunch habits, I found that this method was taking a large chunk out of our budget.

Being a working mum, it was easier to stop at the supermarket on the way home and buy pre-packed salad ingredients, but I soon discovered it was adding around $55 to the weekly budget. Plus, buying cold meat to match everyone's tastes added another $40 per week. I decided it was time to cut down. After doing some homework looking for the best prices and quality, I now purchase a bag of carrots, a couple of fresh beetroot, some fresh bean sprouts and cucumbers and a variety of lettuce. I noticed that by purchasing these items late on Sunday afternoon, I can pick them up even cheaper.

I grate my own carrot, beetroot and cucumber, throw in the bean sprouts and store in the fridge in an airtight container. I tear up the lettuce leaves and mix together in a plastic shopping bag and store in the vegetable crisper where they stay fresh and crunchy all week. My salad ingredients now cost less than $10 per week and they last longer. Throw in a small portion of sundried tomatoes for my hubby and I add approx another $1.50 to my total.

Instead of buying cold meat from the supermarket deli, I now purchase a couple of extra chicken breast fillets from my Asian butchery for around $4.00; this is cheaper than ALDI or any other local fresh meat source. I cook and shred the chicken myself while tinned salmon and tuna add extra variety; a $0.69c tin of tuna covers two lunches when added to salad. I purchase mince when it is on special and make a large batch of meatballs, which are frozen and used over a period of weeks as another filling alternative. Another favourite is home cooked corn beef; rather than putting the leftovers in the fridge, I slice it thinly and freeze for another filling choice.

My three girls are now involved in the Sunday afternoon preparations. Whilst my eldest daughter is madly grating the salad items, I tear up the lettuce and my younger daughters have great fun mixing the meatball ingredients and rolling them ready to cook.

Our family of five is still eating yummy healthy lunches but for $70 to $75 a week less than before!
We also have the added bonus of spending time together while we prepare and my daughters are learning new skills too.

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

We are a family of only two adults who cook often with a large crock pot. However we do find ourselves with a heap of left overs after cooking a pot full of food. So, instead of filling the crock pot with enough food for one meal several times over, we now take two oven bags and divide our meat/chicken/fish between both bags. We add different flavourings to each bag then arrange both bags in the slow cooker and cook on low for eight hours. I have just made Chicken Korma in one bag, using drumsticks that were on special with an extra pinch of cinnamon and some chilli, and Mediterranean Chicken with olives in the other bag. The conflicting smells are surprisingly delightful and the final result is two delicious meals both cooked with the same amount of power I would have used for one. Any extras we don't consume straight away I simply freeze and save for a later date.

My husband and I have set a goal to pay off our mortgage within five years. We have a way to go, but keeping this goal in mind has helped us to curb our spending.

I worked out that any amount I put on our mortgage is actually worth five times that amount due to the saving in interest. So when I am thinking about spending $20 on a top, I multiply this amount by five and realise that I do not want to spend $100 on a $20 top! That $20 would be much better invested if it was put into our mortgage.

We are saving over $600 a year on shoe deodorisers! My husband has terribly smelly feet and is very embarrassed by the problem. It was costing us approximately $12 every week to buy different shoe inserts and powders, all of which were only temporarily effective. Now it only costs us $2.00 every two months! My husband has discovered that just a few drops of waterless hand sanitiser on each foot kills all the bacteria that causes the feet to smell. It takes just a few seconds to apply and evaporates very quickly, meaning no mess on his feet, socks or the carpets. He buys the large bottles of sanitiser for only $2.00 in the bargain stores and they work brilliantly. All his shoes, including his work boots, are now completely odourless!

This idea is for those who live in a home with a garden that is too small to have a compost bin. I use an empty garden pot, cut a square of one of those net bags oranges come in to cover the hole of the pot. Put in a layer of old potting soil (from a pot where the plants have had their day). Each day save your fruit and vegetable scraps in a container. Place in a layer of scraps, then cover with another layer of old soil. Repeat layer by layer until the pot is nearly full, ending with a layer of soil (water as you go).

Then, while the compost is breaking down and baking, plant some seasonal seedlings on top and in no time you will have potted colour and compost underneath, not only feeding your seedlings but ready for the garden when the flowers are spent at the end of the season. I sometimes benefit from crops of vegetables germinated from the seeds in the compost such as tomatoes, cucumbers, capsicum and butternut pumpkin.

This is a multi recycling exercise using unwanted orange bags, unused pots, old soil and fruit and vegetable scraps and, of course, it is a great medium for the latest seedlings. Instead of flowers on top you could plant your favourite herbs while the compost is baking.

Think twice before you buy an expensive bathroom cleaner to clean your acrylic bath, vanity basin and laundry tub. Try Sunlight soap - it works wonders!

After recently having a dint repaired in my three-year-old acrylic bath (the kids were too rough with their bath toys!), I asked a man who repairs acrylic baths, basins, and so on what the best cleaning product was to use on this surface. I was amazed to hear that good old Sunlight soap was the best. He said most of the marketed products available eventually wear the surface and take off the shine, then people have to pay him hundreds of dollars to get that shine back again!

I decided to try it for myself. I purchased a pack of Sunlight soap (four in a pack) for $2.09 at Coles (with even cheaper generic brands available). One cake of soap lasted me for six months - that's just over $0.50c for six months of cleaning the bath, vanity basin and laundry tub. Best of all, it really works! Also, it leaves a wonderful shine; I was really impressed. I use an old sports sock over my hand and foam up the soap, then I clean away - all that soap scum and grime easily vanishes.

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.

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!
