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!

For just $10 I've finally discovered soft skin. I had always suffered from dry skin and, over the years, had spent a fortune on moisturisers in every price range. I never really found anything that I could put on at night which left my skin soft and moist in the morning. It seemed my skin was always thirsty. Then I read in Vogue magazine, about a woman who used Neutrogena Norwegian Hand Cream as a facial mask. She also suffered from dry skin and her dermatologist had advised her to do this. Having nothing to lose, I decided to give it a go myself. It costs well under $10 and is available at Priceline and in most supermarkets. I chose the fragrance-free one and can honestly say it is the best moisturiser I have ever used. I use it every day under make-up and my skin looks 'dewy' all day long. I apply more in the evening before bed and my skin feels lovely in the morning. I even apply it thickly as a mask sometimes, with great results - and it beats a facial in terms of how my skin feels the next day. So if you have dry or mature skin - give it a try. It is also amazing on dry feet - it really is a miracle! It's amazing to think of how many dollars I will save from now on on my new, simple skincare product!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

I'm saving money, time and sanity by serving dinner much earlier – here's how! With three young school children, I was finding they were coming home really hungry from school, eating up and were not hungry at dinner time. This meant I was struggling to find healthy, economical after school snacks and throwing away perfectly good dinners! The solution? I changed our dinner time to 3.30–4pm! They have a healthy, nutritious meal when they're hungry and a small snack such as fruit later in the evening. No wasted dinners, no stressed mummy! I have their dinner ready when they get home and then have more time to help them with homework. They are also helping out more with dishes and so on, which is a great help to me.

I make home-made yoghurt in my EasiYo maker for as little as $0.50c per kilo. You don't need to buy the special sachets, all you need is milk powder and a couple of tablespoons of plain yoghurt. I just use 1 and 1/3 cups of milk powder and two heaped tablespoons of yoghurt (saved from the last batch). Easy, cheap and delicious!

I use polar fleece squares for face washers as they foam up well and are very soft. Recently, the kids had just hopped out of the bath and I noticed that there was a lot of foam on the glass doors (we have a bath/shower combo) so I gave them a quick wipe and noticed that the window came away clean with no streaks. My mother has a shower screen that we have tried every product known to cleaning on over the past ten years with no great success. She tried this and was absolutely amazed at the result! Clean, clear and streak free.

Please try it - just polar fleece and warm water. You will save a fortune as polar fleece is only about $6.00 per metre (buy good quality as it will work better) and you will not need to use any more toxic chemicals. I also use polar fleece as nappy liners, general cleaning cloths, and dusting and dishwashing cloths. Great for cleaning and polishing stainless steel also!

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 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!

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.

I have saved a fortune on laminating costs over the years, by doing my own at home. I don't have a laminating machine though - I don't need one! I just buy the laminating pouches I need and get exactly the same effect using my household iron on a low setting. You just need to ensure you are working on a fairly rigid surface - if your ironing board is too 'spongy', strengthen the surface by adding a piece of cardboard, covered with cloth before laminating. When applying the iron, put a cloth or other fabric between the plastic and the iron. The results are just the same as using a machine and the heat will gently fuse the pouch together. I have done this for so long, that I don't know how much laminating costs any more, because I never pay to have it done!
