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!

Renovations need not cost the earth. We just bought our first home and it had a hideous old kitchen with brown contact, broken stove elements and musty cupboards that had seen better days. We wanted a new kitchen but it was going to cost $4000. It was money we didn't have, so I used my brain instead and renovated our entire kitchen for under $100.

I bought:
Two bottles of oven cleaner at $3.99.
One second hand element from the dump for FREE!
Two tins of paint from Kmart for $17.99 and $36.99
Curtains that were faulty and discounted to $20 for two pairs.

I stripped off all the contact, cleaned the cupboards and painted the inside with flat acrylic paint. They are now white and clean inside. Then I cleaned the oven and fitted the element from the dump. It looks great. Now the oven will do us until we get that mortgage out of the way! I then removed the cupboard doors and gave them a coat of enamel paint. I took the door handles off, cleaned them with oven cleaner and refitted them - they came up like brand new! Finally I hung my bargain curtains and my new fresh, white kitchen looks lovely.

My husband was very impressed. All it took me was two days work and $82.96 of supplies. Best of all,I saved $3900 on a new kitchen.

I found a way to save almost $50 a year on liquid hand soap with hardly any effort! Just take a bucket filled with four litres of water. Drop a bar of generic soap into it and let it soak for 24 hours. Give it a mix and pour into clean two-litre milk bottles. Just top up pump bottles when needed. For a little added luxury, add half a cup of sorbolene cream and a few drops of glycerine. Works a treat!

We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

Changing circumstances and a growing familly all added up to us paying a whole lot less off our mortgage than we would have liked. Pretty soon we would have started to go backwards. It was crunch time!

Using the Simple Savings calendar I identified our most expensive habits, and was astounded to see the amount of money that could have been saved. Our grocery bill was always around $200 or more per week. This amount did not include meat or bread that we get from the butchers and bakery.The trouble was, my husband loved all the expensive name brands for items such as chocolate biscuits, lollies and savoury snacks and was convinced that the cheaper or no name products would be tastless and boring. Week after week I would just automatically reach for these items, without even glancing at the alternatives. I knew as soon as my husband saw the packaging, the goods would remain in the pantry unopened, and he would then go and buy the brand name items anyway.

One week I kept mentioning to him that I was going to do a big clean up of the pantry and I was finally going to utilise all those assorted Tuppaware containers that I had never used. That week I substituted his expensive brand of snack foods with cheaper versions, emptied them into the assorted airtight containers and threw the plain packaging out before he could see them!

I also applied this technique to several other items; I would fill cheaper dishwashing liquid into Morning Fresh bottles, no-name hand wash into saved Palmolive dispensers, you get the picture. Our grocery bill went down from $200 to $140 per week - a saving of $240 a month!

When I finally fessed up to what I had been doing, my husband admitted that most of the snacks were just as good as the name brands, you just have to try a few out. All it took was some creative (OK, and somewhat deceitful) way to present the changes, but we have never looked back. Why would we, with a saving of $3120 a year? Plus of course, one very neat pantry!

I can make four litres of handwashing gel soap for under $1.00! To make your own liquid gel soap, grate a bar of Sunlight or generic laundry soap into a two litre ice cream container. Pour boiling water to half fill the container and mix to dissolve the soap. Carefully fill to the top with boiling water and mix well. Pour half the mixture into another two litre container and top up both with boiling water again. The gel is very thick once it sets, but a good consistency for its purpose. Store in the two litre containers and refill pump bottles as needed. One pump is all it needs to clean your hands and can even wash dirty dishes if you squirt into the sink!

Saving $1.00 a day has helped me afford things I would have otherwise struggled to pay for. I started doing this when my sons started at a private school in the city. They would be invited to several birthday parties throughout the year, so to ease the financial burden of gift giving I used my money box. At the end of the year I would use whatever was left to buy school supplies for the following year.

My children have left school now but I still save my $1.00 a day which I use to treat myself to a pedicure, go to a movie or have coffee with friends. It's such a small amount each day that I find it doesn't really affect my household budget, but it always came to my rescue when I needed it, and now affords me my treats.

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

My mother, sister and I have changed our spendthrift ways to help each other out and enjoy quality time and a regular meal together.

We used to spend our weekends shopping. Of course we bought things we did not need. Even worse, we spent tons of money on eating out in the mall! So, we changed our habits! Once a month we spend a day at one of our houses, taking it in turns. The hostess is responsible for lunch and the others help her with a project around her house.

For example, we have painted a playroom, done general cleaning, cleaned a garage, collected items for charity and more!

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.
