One year a friend gave me a money tin and on the side of it was printed, 'If you fill this tin with only gold coins by the time it's full you will have at least $500'. It really didn't look big enough to hold that amount of money, but I love a challenge so I decided to find out if it could!

We started in March and any gold coins we had went into the tin. Our goal was to open the tin at Christmas and use it to pay off lay-bys plus have some spending money over the Christmas break.

November rolled around and the tin wasn't quite full. However, when we opened it up and counted our 'gold' we were very surprised and extremely happy to discover we had collected $700 in our little tin!

Because of that little treasure chest of gold we enjoyed a fantastic stress-free Christmas! I was able to pay for all the presents for our immediate and extended family as well as cater for a great Christmas day feast, AND we had spending money left over for the holidays.

Now it's a family tradition. My sceptical husband happily donates all his gold coins to the tin and my 12-year-old will go hunting for gold coins just to add them to the collection! I know that I don't have to worry about the financial strain of Christmas any more as my tin has got it covered.

As a new singleton, I have learned not to let my pride stand in the way of making a new home for myself on a budget. I recently separated from my husband of 14 years and moved out of the family home. We share our four children week-about but I wanted to leave the family home as complete as I could for some sort of stability for the kids. With so little to now call my own I had no choice but to swallow my pride and 'put it out to the universe' that I needed quite a bit to furnish my new home.

At the op shop I purchased three Jason recliners, a telephone table, two tallboys, a desk, four bedside drawers, a single mattress and linen for the beds for $63, including delivery!

By word of mouth through friends I was given: a washing machine, microwave, crockery, glasses, towels, THREE TVs and a TV/stereo unit, a digital set top box, two stereos, a BBQ, a brand new gas bottle for the BBQ, a gorgeous white cast iron bed for my daughter, a queen size bed and three single beds, a computer, a bookshelf, a two seater couch, a bike and doonas for us all, as well as pillows. I gave away a few of the TVs and one of the stereos to people who needed it.

I also found that if you ask your friends if they have excess tea towels, coffee cups and so on, you'll find that they can often spare a few of these items.

Most importantly of all, I have learned that I don't need matching crockery or linen to make a home, just the basics and a lot of love!

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!

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.

I recently noticed my elderly neighbour was unwell and no longer able to drive or leave the house; relying on taxi services to deliver food (often expensive pre-packaged items), or he would have home delivered takeaways. Being a fussy eater, he was reluctant to consider 'Meals on Wheels', so I volunteered to shop for him and cook him three different meals a week. Each week he gives me enough money to cover the costs of his meals (soups/stews/freezable casseroles) and I make up bulk amounts of each dish. I deliver half to him and keep half for myself, as suggested by him for payment. Not only is he saving money on taxis and home delivery, but he is eating healthy food and my family is also provided with three meals a week as a bonus for giving up a little of my time. Often cooking for one is not inviting, but cooking for others encourages healthier eating habits and helps regain social contact. Often a lonely person will gain a new lease on life to boot. A great savings all round, and using recipes from the Vault saves me even more!

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!

We had the chance to travel overseas several years ago but had to save $1000 to make it happen. On one income with two small children it seemed impossible. Then I had the brainwave - I didn't have to save $1000, I had to save $1.00 a thousand times! This was so much easier - a generic brand product at the grocery store, a chocolate bar at the petrol station and so on, soon added up and the savings contributed to a great family holiday.

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!

I have two daughters who live at home with me who are both university students. They both work part-time and pay me $50 a week each for everything. (And I mean absolutely everything!) I had begun to get sick and tired of their wasteful habits! I would find half eaten muesli bars lying around, week-old uneaten fruit, discarded shampoo bottles and toothpaste tubes with enough in the base for three or four more uses, soap in the bin which still had plenty of use left in it and the list goes on! Quite frankly, I'd had enough! I told them to keep their $50 a week and instead they could buy everything for themselves (snacks, lunches, toiletries and so on). I would provide their one evening meal and that was it. I even made them buy their own toilet paper. Well after two weeks they have decided to mend their ways! They just did not realise the costs involved in running a household and admitted they had taken things for granted. I only wish I had done it much sooner, for their benefit and also mine! One daughter can only afford to give me $50 still and her older sister has increased her amount to $70. However, I think things around here are going to be very different from now on as my Sad Sallys strive to become more like Happy Hanna!

This hint was a saviour during our last $21 Challenge.

The girls were looking for lunch and complained there was nothing to eat, so I found a large plastic platter and put the following treats on it:

A leftover BBQ sausage, thinly sliced

Two slices of leftover bread, buttered and cut into quarters

A diced kiwifruit

Four strawberries

A small piece of cheese, diced

1/4 tin corn kernels in a lettuce leaf

A muffin, cut in quarters

Four leftover chicken nuggets, cut in halves

A dob of cream cheese with a little corn relish mixed in

Four cucumber slices

Four cherry tomatoes

One Vita Wheat, halved

I gave the girls and myself a saucer each, plus a cocktail fork and everything was eaten and enjoyed. Now we often have 'platter parties' for meals and snacks. A novel way to serve up a meal when you have 'nothing' to eat!
