I came up with a great low cost, low stress way to feed the crowds at my son's 21st birthday party. With the weather being chillier, the food needed to be warming and more robust than usual. I came up with the idea of a crockpot party! I am borrowing family members' and friends' crockpots and am filling them in the morning with different dishes, then I can 'forget' about them until the evening! When it's time for everyone to eat, I can then just plug them all into a power board and put them on the table. This is a triple whammy saver for me! It saves time as I don't have to spend all day in the kitchen and can get other things ready for the party instead. It saves money as I can use cheaper cuts of meat to achieve tender dishes and - as I don't have to use serving dishes, it even saves on washing up!

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!

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.

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!

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.

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.

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

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!

I moved to Perth a couple of years ago with very few possessions, two young children and a dog. I stayed with friends for a couple of weeks and really liked the area they lived in.

I set my rent limit to $150 (cheap for city living - but necessary for the budget) and put my name down on the huge waiting list for government housing. I looked at many places - most out of financial reach. The ones I could afford looked (and smelled) bad. I decided I could 'change' the appearance and the smells - but not the budget.

So, I rented the 'worst house in the best street'. I went through a real estate agent and asked if I could meet with the owner. When he came around (which most don't do regularly with managed properties), he was the first to admit the place needed work (mostly cosmetic).

I suggested to him that I would spruce the place up a bit and in return my rent would not go up while I lived there, plus we agreed that I would be entitled to two weeks rent free over Christmas!

I have painted the entire inside of the house for about $200 (including feature walls, and old laminated cupboards) by buying mis-tinted paints and laybying paint specials. I ripped up the old carpets and polished the floor boards (about $150 in equipment hire and food for my 'helpers') I also got second hand carpet for free from the local paper and replaced the old stuff in the kids bedrooms. I got curtains and blinds from the op-shop and sale tables (about $50 in total)

As for the outside - my place looks better than most of the privately owned homes now! A few boxes of lawn seed (about $3.00 from supermarkets), a bit of hand watering and weed pulling and I have a great front lawn.

I built flower beds with bulk seedlings ($0.45c per punnet from the local nursery - discontinued or 'sick' stock). People in the street are always telling me how great the house looks and they can't believe its the same place!

I work and go to university, as well as look after my children - so all this has been achieved over the last two years. My landlord is happy, we are happy and the money I save weekly in rent (between $50 - $60 per week) allows us to go on holidays once a year and have a few extras!

We are retirees. We eat well, dress well, and live in a modern house, with an interesting flower and vegetable garden. Our income would probably be classed as poverty level, but we live like kings, because we have one shared vice. We are garage sale fanatics. Little in the house has been bought new. Older furniture has been restored, as my husband has clever hands. Once a year he sells the surplus at a huge garage sale, and it usually pays for a holiday.

We buy books, linen, furniture, new clothing, garden plants, sewing material and cottons, timber for building toy boxes and hall stands at garage sales. Our kitchen TV cost $25. The little one in the bedroom is 25 years old, so I bought a video recorder for $5.00 and can now get all the channels through the video. My three telephones and the answering machine are all from garage sales, as are my kitchen crockery, blankets and the beautiful satin embroidered bedspread that cost $5.00.

I am like a centipede with shoes as I buy good brands that have been tried on in the shop and are as new. It is the only place I can find the good comfortable shoes I favour. Likewise, many of my clothes are top brands. I bought a $168 pant suit for $10 because the lady's husband didn't like the colour.

The deep freeze, the two coolers, bed lights, beautiful big mats are all from our Saturday morning treks. We list the sales and use a street map to plan a route to save petrol.

Sometimes tinned food or home-made sauces are available, and if the vendors have fruit trees they sometimes sell the fruit by the plastic bag - picked yourself.

Nothing is sacred at garage sales, and provided you need the items there are some real bargains.

How about our home security system for $2.00, because the seller couldn't work it? A little investigation on the Net yielded full instructions.

My computer came from a government auction at one-third of the price quoted for a second-hand model at our local shop. Needed a bit of study to set it up, but I love puzzles, and so had it running with the Windows 98 program I bought for $10. I also keep the grandkids in Playstation games, and my daughter has been married for 20 years and has never bought any linen as I have kept her supplied with good quality buys.

My hobby started after my divorce when I found myself with an old 50's house to renovate and little furniture. So I started to buy 50's vintage furniture as well as renovating materials - paint, wallpaper, timber, doors, curtains.

Along the way I met a widower with the same ideas, so garage sales have provided a lot of rewards - a good life, enough money to enjoy ourselves, and a multitude of associated hobbies and friends.
