I am no longer wasting leftover avocado, thanks to this simple storage tip! I have always loved avocado but could never use a whole one in one go. I would use about a quarter for my lunch but by the time I went to use the rest it would have gone brown and didn't look very appetising! Avocados can be quite pricy so the expense of wasting so much was very annoying. Then my new partner, who is chef told me how to stop the browning! I didn't realise but the longevity of avocado is due to light. He advised me to wrap the avocado in aluminium foil and then wrap it in cling wrap and put it in the fridge. To my surprise it really works! Now I get to enjoy ALL my avocado and save heaps too!

I am a 39 year old mum with five children. I love to have soft skin, but I'm not keen on all those chemicals in general moisturisers. I like natural skin care creams, but they come with a hefty price tag. Thankfully, my grandmother gave me a perfect, all natural solution.

She suggested I try coconut oil, as she had used it as a skin moisturiser and hair conditioner while she was growing up. I purchased a 400ml jar of organic coconut oil from my local health shop for $10.70. I now use it every evening on my face, and every morning as a body and face moisturiser. I also use it as a lip balm and once a fortnight, I melt 1/4 of a cup and apply to damp hair. I then pop on a shower cap, wrap my hair in a towel and experience a moisturising hair pack that smells divine.

My skin has never looked better and my normally dry, curly hair is now soft and shiny. The jar I purchased six weeks ago is still half full and I estimate I will save $380 a year on moisturisers, hair packs and lip balms. Best of all, it's chemical free.

Christmas 2009 was the worst I ever had, having just separated from my husband. At almost 50 I found myself homeless with no money. On the 16th of December I found a share accommodation but had to borrow money from friends to pay for my bond and two weeks rent so that I could have a roof over my head. The only job I was able to do to keep me going was as a housekeeper, yet I could hardly pay for the petrol to get to work.

For four weeks, I avoided going to the shops. I am 90% vegetarian so decided to grow all the vegetables I like to eat at my rented home. I collected some seeds, seedlings and cuttings from friends and customers and decided to spend my last $10 for chicken wire to protect my homegrown herbs and vegetables from possums and bush turkeys. I am spending time tending my garden every day and I now have lettuces, beans, cucumbers, cherry tomatoes, herbs and so on for salads and stir fries every day. I even have enough to give some to my friends and customers to thank them for helping me to stand on my own feet and living a healthy life. This week I only spent $16 for organic eggs, milk, a tin of pink salmon and a loaf of bread. These with my homegrown herbs and vegetables will give me a healthy diet for the whole week. I am saving heaps to pay my debts as fast as I can.

At soon-to-be-50 and with no savings, I bought The $21 Challenge book to challenge myself. I am so excited because I spent years of feeding a family of four and now I am alone I have absolute control of what I spend and what I put in my mouth. I feel liberated, I feel young and full of energy. Having less money in 2010 is more enjoyable than my stressful life in 2009!

I am 22 years old and on a low income, but am well on the way to saving for my first house! I developed a simple system that keeps my savings goal at the forefront of my mind and encourages the support of those around me.

I've always found it hard to save, but one day I got a big piece of cardboard and wrote 'My House Deposit' at the top. On the right hand side I cut out images of a house, a kitchen and a loungeroom that I would love to own one day. On the left hand side I drew a giant thermometer and on the side wrote the figures $0 to $40 000 ascending, just like on a real thermometer. Whether or not I need $40 000 is irrelevant; I look at this table every day and whenever I save another $500, I colour in with a red crayon up to the amount on the tally. I use hints from Simple Savings, such as making my own lunch every day and not buying clothes if I don't need them and now whenever I make a purchase I think of my house deposit and how much I want it far more than a coffee or new shoes!

An unexpected bonus of having this chart is that I've found my family and boyfriend have become aware of my goals and I get lots of support along the way. This visualisation technique really does wonders, and most importantly you are making a concrete agreement with yourself and you stop losing sight of your goals. I'm already a quarter of the way to reaching mine!

We have saved hundreds of dollars on making our daughters' room cosier! We are living in a rental property which we really like. However, our daughters are in the front bedroom and although it has a window, the room itself it doesn't get a lot of sunshine. This makes the room rather gloomy and feels damp in winter. We have a small heater which we use to try and take the chill off the bedroom before they go to bed but using it makes us feel we're watching money disappear before our eyes!

The perfect alternative would be spend hundreds of dollars on installing a skylight but since we're only renting, this really isn't an option.

A couple of weeks ago, I bought a couple of mirrors for $4 each to stick on the inside of a wardrobe. While I was preparing the area, I put the mirrors on the windowsill and to my astonishment, noticed how much brighter the room was when the sun hit the mirrors and bounced off the ceiling. It was as though I'd switched on a light!

By using those two mirrors and angling them slightly, I was able to bring sunshine and some warmth into the room. I have since purchased two more mirrors to make sure I take full advantage of the entire time that the sun hits the windowsill. The room is heaps brighter and feels more cheerful and warmer. It only cost $16 and it was all done with mirrors!

Instead of buying Christmas presents this year, I asked my parents to write a 'book' for their grandsons. My boys love listening to bedtime stories so I thought this would be a great way for them to learn more about their grandparents and what they did when they were younger.

At first, my parents didn’t know what to write about, so we went through old photographs, scanned them into the computer and they wrote about what was happening in the pictures. We didn’t just use the usual photos like wedding pictures, but chose lots of candid shots and even photographs of places that evoked memories for my parents.

In the process of putting these books together, I learned things about my parents that I didn’t know and it made me realise that the 'book' would also be a perfect Christmas present for my brother and his family. So, for the cost of a few sheets of paper and some printer ink, I have an inexpensive gift that is priceless!

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!

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!

My husband and I have set a goal to pay off our mortgage within five years. We have a way to go, but keeping this goal in mind has helped us to curb our spending.

I worked out that any amount I put on our mortgage is actually worth five times that amount due to the saving in interest. So when I am thinking about spending $20 on a top, I multiply this amount by five and realise that I do not want to spend $100 on a $20 top! That $20 would be much better invested if it was put into our mortgage.

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!
