Slash your washing powder costs by using a tablespoon of washing powder in your machine instead of a scoop. It works just as well! My sister was learning about budgeting and the speaker mentioned that you could get the same wash results by using one flat tablespoon of washing powder as you could if you used a whole scoop. I decided to test this theory and found that even with a full load of washing this proved to be true. I buy a top brand washing powder that costs around $10 per two kilo box and it contains around 148 tablespoons. I used to go through a two kilo box of powder every four to six weeks when I was using a scoop. Generally I do a load of washing every second day, so using one tablespoon per wash, my box of washing powder should now last me nearly 10 months! Just changing this small habit will save me $90 every 10 months on washing powder!

I took on the $21 Challenge, and won! However, my husband was a rather grumpy participant; he loved the savings but not the lifestyle during Challenge week. As he goes away regularly, I decided that every night he's not home for dinner would become a $21 Challenge night for the kids and I - all meals must be made from ingredients I already have at home, and I can only use ingredients that have not been allocated for other meals. This saves money and gives me a night off cooking, as my Challenge meals are usually simple affairs, sometimes as easy as pancakes or toasted sandwiches.

The true value of the $21 Challenge became apparent when a friend was recently diagnosed with a severe form of leukaemia. She is a married mother of four boys and is embarking on a long therapeutic journey that will hopefully lead to a full recovery. As a way of helping her family, the parents at our school have banded together to make all their meals for the next three to six months. As they are a large family, with an above average food requirement, I was unsure how I could afford to help feed them each week. Thankfully, my husband was away the week my friend was diagnosed, so the kids and I lived off the $21 Challenge that week and all leftover money was put into making meals to freeze for my friend's family.

We now do the same thing whenever my husband is away – it's a great gift over the Christmas break to know that I can afford to cook and freeze meals for my friend's family, and look after my family at the same time. Thank you.

If you have an old bookcase that you no longer need, or is a little too unsteady to use as a bookcase you can transform it into a super cheap underbed storage container! All you need is to buy some castors from your local hardware store. Just screw the castors onto the back of the bookcase, lay it down on its back and roll it under the bed. We have one of these in our boys' room for all their toys and it really reduces all the visible clutter. It's lovely to walk in and all you see are their beds!

Going out of my way to present well to prospective landlords has really paid off for me. I recently had to find a new rental property and found that the open inspections where attracting many families at a time. Being a single mum of four, I knew I had my work cut out for me trying to get something over the two-parent families.

I decided I would write a covering letter as an introduction to the land agent/owners. I wrote about who we were and even what schools the kids went to, to show we were already established in the area, where I worked for the same reason. I got friends, my employer and my pastor to all write character references for me, which I copied and added with the letter. I also have a dog, which can be a problem so I got my then-current agent to write a reference for my dog too, which I also copied and added with the letter. I then attached these to the application, along with copies of my last four weeks' payslips and a payment summary from Centrelink.

The first house I applied for had more than 20 families and most of them were two-parent families. I added all the above mentioned stuff to my application and I was happy to receive a call the next day to say I was successful. I asked the agent if my letters and other details had helped and he told me that they had been the deciding factor. They liked that I had taken the extra step and cut out some of the work for them. They also appreciated that I had been so open with them. I would recommend this to anyone trying to rent a place. It takes only a little time and effort but could be just what you need to secure a house!

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.

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 held a very successful and inexpensive party for my daughter and her 12-year-old friends by doing my own version of the 'Amazing Race'! When sending out invitations, each person was allocated a team colour and asked to wear clothing in that colour. On arrival they were given a back pack containing water bottles, maps of the town (we live in a small town and had all activities within a few blocks of home) dry biscuits to snack on, a list and bag for a scavenger hunt to find things on their travels, a dictionary, sunscreen and their first clue.

I had friends in the area lined up with different tasks to be completed (these included windows to be washed, shooting a set amount of goals at a basketball court, sorting books into alphabetical order, separating peas and corn with chopsticks and many other easy to prepare tasks). Each team had a passport to be stamped when each task was completed and the next clue was handed over at each destination. For the final clue, they had to use the dictionary to work out the coded directions to their final destination - our local swimming pool where they spent a couple of hours playing around before heading back to our place for the party food!

This party really didn't take much to organise once I got into it; just a few friends willing to give up a little time for each task and some imagination. I used items from home to make up the challenges, such as books, jigsaws, basketballs and frozen vegies. It was talked about for weeks afterwards and I used photos from the day to make a photo slide show, which I burnt onto discs for everyone who came!

We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

I have turned my love of a good bargain into something far more valuable! Whenever I am tempted to buy something I could possibly do without, I first calculate how much we would save by paying that money into our mortgage instead. For example, I recently saw a new dress on sale for $49.99 - a bargain, right? However, I paid a quick visit to a mortgage calculator website and discovered that if I didn't buy the dress and put that money onto our mortgage instead, it would take a whole month off the loan term and save us $334.39c in interest. In other words, my 'bargain' dress would really cost me over $300!

Looking at my purchases this way has become a really easy and effective way to curb my spending habit. Now I carry a piece of paper in my wallet with various prices on and I can see how much I would really be spending. It's amazing how much stronger my willpower becomes when I check my piece of paper before buying something and find out what its real cost is!

Use this one basic mix to make scones, scrolls, pikelets, pancakes and waffles! It will save you heaps of time and heaps more money!
