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.

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?

Keep glass showers sparkling clean for months at a time by using baby oil. First, clean the glass on the inside of the shower well, then dry off. Next, take a soft cloth and smear a small amount of baby oil. I stress a SMALL amount to ensure no oil runs down to the base of the shower, creating a potential hazard. Pay extra attention to wiping the edges and bottom of the glass. Once you have done this, the glass will look smeary and quite awful really - until you have the next shower! The hot water heats the oil and smooths it out on the glass. I have never had the problem of any oil running down onto the floor, even after heating it. You'll find a very small amount goes a very long way. Basically, the soap scum cannot attach itself to the glass, which stays clean and clear for at least three months at a time. By needing to re-apply the baby oil only every few months, this adds up to a huge saving in expensive bathroom cleaners!

Three weeks ago we ended up without a cent to spend on groceries and the money situation for the following week was only slightly better. We had to eat, of course, so I raided the pantry and freezer and managed to get by on what we had. We were also running out of laundry powder and toilet paper so I rationed out these things to make sure we made it through until we could afford to stock up. It meant using less laundry powder per wash and a few less squares of toilet paper each visit, but we got through the week without having to buy anything, saving around $300.

The following week we had only $30 for food shopping. I still had things I could use up in the pantry and fridge/freezer, and the rationing of the laundry powder and toilet paper meant we wouldn't need to buy more until the next week. So I spent our $30 surplus for that week on milk, fruit and vegetables.

Last week we were back to normal but my two weeks of poverty made me realise just how much money I can save each week by using less of everything and trying to use up what I already have in the fridge and pantry. Over two weeks I had managed to NOT spend about $570 and I had also cleared out a stack of canned beans, canned tuna and sardines, frozen vegetables, frozen meat and frozen loaves of bread that were taking up space in my pantry and freezer.

Transforming myself from a shopaholic to a smarter consumer has enriched my whole life. Not only am I saving money, my life has become deeper and more meaningful since I decided to live by the following rules:

• Keep away from the shops.
• Buy only what you need.
• Buy second hand if you can.
• Be stylish, not fashionable.
• Don't buy what you can borrow.
• Stop reading glossy magazines that encourage shopping.
• Borrow books and magazines from the library.
• Read about simple living.
• Do it slowly.
• Spend more time with your family and friends.

These rules may sound simple, but they have changed my life. For as long as I can remember, I have loved shopping. I could easily do it all day, every day and never tired of it. I enjoyed the quest to find bargains or something I had 'always' wanted or didn't yet have.

When I felt angry, sad, lonely, fat, old, poor, disappointed, rejected, embarrassed or simply 'not good enough' - I went shopping. It made me feel better.

When I felt happy, confident, rich, delighted, loved, appreciated and 'on top of the world' - I celebrated by going shopping.

Although I work full time, I had never paid off my credit card and financially I was always struggling. Then I heard about climate change and the impact my shopping was making on the environment. That's when I decided I would stop shopping all the time.

At first, this decision left an enormous vaccuum in my life. I used to be very busy - 'Never enough time in the day' was my mantra. Then suddenly I had lots of free time! I didn't have many really close friends, except my mother and sister. We often used to meet for a coffee and a chat while we were out shopping. But with all the free time I now had, I realised I had been too busy to make other meaningful friendships because of my constant shopping.

I don't meet my mum or sister at the shops any more. We now get together in each others' homes and, although I have always enjoyed their company, I rediscovered a deeper connection with them. We talk, laugh and cry for hours and hours. I am learning so much more about them. I have started to deepen the friendships I have with people who were just 'acquaintances' before. Instead of shopping, I invite them over for a cup of tea or lunch or for a walk along the beach. I'm even starting a book club.

Due to the money I was able to save from not shopping so much and because I wanted to entertain more, I rented out my small unit and moved to a lovely old house. However I soon realised I needed more furniture, so I bought it all very cheaply, secondhand from eBay. Everyone who visits my home says how wonderful and stylish it is. I love making cheap, affordable meals for my friends. I had my first party on New Year's Eve and 35 people came, each bringing their own meat, drinks or salads. To any shopaholics out there like me, it IS possible to change - I'm living proof!

Simple Savings has become a way of life. I don't have to think about saving or spending now - it just comes naturally. In the past five and a half years, we have managed to pay a whopping $150,000 (principal) plus interest off our mortgage and still live happily and comfortably. This is all due to Simple Savings.

My husband and I have three young children and our combined income is only average, ranging between $50,000 - $70,000 per year. Readers may think 'I could never do that, I would have to go without too much' or 'that's impossible', but this is not true. We don't go without; in fact we feel we do pretty well! I cannot name just one single thing that has helped us to achieve this and still be happy - it is a multitude of tips and hints, all of which can be found on your site. I have always been a Simple Saver, so for me this was not hard, but my husband found not being able to spend money willy-nilly difficult at first. These days, I am proud to say he thinks before he spends and at times even proudly tells me of his smart purchase or why he didn't purchase!

I could go on and on giving examples on how to do what we have done, where we saved money and how we used it more wisely, but that would make a book and to be honest all people have to do is log on to your site, it's all there. Focus on your goals, walk hand in hand with Simple Savings and your dreams can come true.

I no longer use disposable cloths to wash the dishes and wipe down benches.
 
I recently bought two bulk packets of face cloths, giving me eight cloths. Each cloth is the perfect size and thickness for washing dishes and wiping down benches. I use a cloth for a day or two and then throw it into the wash with the tea towels.
 
I have been reusing the same cloths for over a year – just think of the savings now that I'm not buying disposable kitchen cloths every month!

I used to buy a large can of air freshener ($42 per year) plus a can of Glen 20 each month ($71.52 per year) for my home and bathroom. On top of that I would also buy a large spray bottle of Febreeze quarterly ($54 per year). That is a total of $167.52 just for freshening the house each year.

On top of that, there was the additional cost of $9.00 a week on floor washing cleaners and disinfectant ($468 per year). A grand total of $635.52 per year.

Now I buy two large bottles of eucalyptus oil ($22), plus I have bought two very sturdy two litre capacity spray bottles (at a once-off cost of $18).

One bottle is reserved for carpet, bathroom and fabric deoderising and freshening, which now has us enjoying the additional benefits of no fluorocarbons or chemicals being used in our home, and eucalyptus oil is twice as effective when it comes to fighting bacteria. I use two tablespoons of eucalyptus oil per two litres of boiled, spring or filtered water.

The second spray bottle is used as a floor sprayer. I now don't use a bucket and mop. I just sweep the floors, wet the mop, spray the floor as I go with the eucalyptus and, hey presto, clean, deoderised and disinfected floors in one easy go. I use four tablespoons of eucalyptus oil per two litres of boiled, spring or filtered water.

The total cost saving for an entire year has been $448, which is now being spent on music lessons for our children. The house always smells fresh, the floors are cleaner and we've had fewer colds than ever before.

I was usually a pretty prudent shopper but was always looking at the money I saved as potential cash for more purchases. This meant that in the long run I didn't really save anything and ended up with a heap of things I didn't really need.

I started taking a 'savings purse' with me to the supermarket when I did my grocery shopping. Instead of buying the product I would normally have bought, I would choose the cheaper alternative. For example, I would purchase the 'home brand' biscuits for $1.00 less. That $1.00 would go into my head as a saving. At the end of that shopping trip I would put any 'savings' into the savings purse. I was stunned. After two weeks of shopping and 'saving' this way, my savings purse contained $100.

I began to use my savings purse in other ways. If I managed to refuel my car with cheaper fuel, I would put the difference in the purse. If I wanted a chocolate bar, and I resisted buying it, I would put that money in my savings purse. Even with those small amounts, the savings became huge. Doing this began to be fun; it was a challenge to find extra ways to put money into my savings purse!

To top it all off, not only was I saving money but, by 'resisting' the sweets and chips so that I could put the money into my purse, I was also eating healthier and losing weight. I am so happy with the results.

I have found a great way to stop impulse buying. I turn the money I would have spent into a 'roundtuit'. A roundtuit is one of those things you always put off and say you will get 'around to it'. Have you always wanted to learn to ride a horse or treat yourself to a massage? Or buy an art print but, because of the expense, have never got around to it? Well, I now put the money I would have spent on impulse buying straight into my roundtuit fund.

Instead of buying that glossy magazine, I look at the price and I put that amount into a special pocket in my wallet. I try and jot down what I nearly bought as well. When the time comes to buy the art print I have always wanted, I can see that it was worth two magazines, a fast food lunch, a shirt on special and a home delivered pizza. I don't feel guilty because the purchase has been funded by my roundtuit fund.

I no longer waste money on stuff I don't really need and I can also see where I am most likely to waste money, which will hopefully protect me from temptation. Most importantly, I'm able to achieve my dreams, almost without realising it. It's a great way to save for what you really want, so isn't it about time you got around to it?
