I was usually a pretty prudent shopper but was always looking at the money I saved as potential cash for more purchases. This meant that in the long run I didn't really save anything and ended up with a heap of things I didn't really need.

I started taking a 'savings purse' with me to the supermarket when I did my grocery shopping. Instead of buying the product I would normally have bought, I would choose the cheaper alternative. For example, I would purchase the 'home brand' biscuits for $1.00 less. That $1.00 would go into my head as a saving. At the end of that shopping trip I would put any 'savings' into the savings purse. I was stunned. After two weeks of shopping and 'saving' this way, my savings purse contained $100.

I began to use my savings purse in other ways. If I managed to refuel my car with cheaper fuel, I would put the difference in the purse. If I wanted a chocolate bar, and I resisted buying it, I would put that money in my savings purse. Even with those small amounts, the savings became huge. Doing this began to be fun; it was a challenge to find extra ways to put money into my savings purse!

To top it all off, not only was I saving money but, by 'resisting' the sweets and chips so that I could put the money into my purse, I was also eating healthier and losing weight. I am so happy with the results.

After reading every newsletter on this fantastic website, I decided to make changes to our household budget.

I started by rummaging through the cupboard, where I found an insulated plunger coffee mug that my husband and daughter had given me as a gift. The mug had never been used as I found it easier to grab a 'latte to go' on the way to work. I bought a tin of ground coffee beans for $6.65, figuring that this tin, with its plastic lid, could be refilled. I now keep this tin in the fridge at work. So, instead of buying three lattes a week at $3.50 each, I now allow myself one a week or sometimes just one a fortnight.

While buying my latte I would sometimes purchase an English muffin with bacon and egg. I now have muffins in the freezer, bacon rashers trimmed and have perfected the three minute poached egg. The bacon takes one minute in the microwave and the muffin is toasted in no time. If I am in a hurry, I wrap the bacon and egg muffin in a small piece of alfoil and take this to work. So instead of paying $14 per week, or $672 per year, I now buy the ingredients for the equivalent of $1.45 per week, saving just over $600 per year. Wow!

You have no idea of how proud I feel. I have saved so much money and it's thanks to your wonderful site.

I can make four litres of handwashing gel soap for under $1.00! To make your own liquid gel soap, grate a bar of Sunlight or generic laundry soap into a two litre ice cream container. Pour boiling water to half fill the container and mix to dissolve the soap. Carefully fill to the top with boiling water and mix well. Pour half the mixture into another two litre container and top up both with boiling water again. The gel is very thick once it sets, but a good consistency for its purpose. Store in the two litre containers and refill pump bottles as needed. One pump is all it needs to clean your hands and can even wash dirty dishes if you squirt into the sink!

I grow most of our vegetables to eat healthy and save money. I save all scraps to compost and I wanted a tumble composter. They turn lawn clippings and scraps into compost in 14 to 21 days. The composter is priced at $410. I bought a 240 litre plastic drum (cherry bin) from the local trash and treasure market for $5.00. My husband drilled holes in the lid. It doesn't have a frame but I roll it on the lawn for five rotations once a day and I make compost in 21 days. It isn't hard to roll but I can't empty it into a wheel barrow (I'm only five feet tall) so I spread a sheet of plastic on the lawn and tip it out onto that. The compost is fantastic.

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

This Christmas, I have saved myself over $1000 on buying gifts AND was able to afford a holiday for two to Queensland, just by using my green thumbs!

Instead of spending $50 on each Christmas present this year, I decided to use up some of my left over garden pots. I wrote a list of all who would receive presents this year and allocated a pot for each person (I also set aside five extra pots for those last minute gifts).

I thought about each person and what might compliment them, then I set to work! My garden is full of herbs, so I took cuttings from each herb and began growing them in their new pot for their new owner. I gave them plenty of time to settle in by Christmas.

When it comes time to give these lovely potted herbs as gifts, I also attach a recipe, so the recipient knows how they can incorporate their new plant into their cooking, or make up a lovely hand cream or bath bomb.

If you have herbs of your own and pots sitting around it's a great way to put them to good use. These lovely gifts didn't cost me a cent! I already had the herbs in my garden, the pots in my shed and instead of buying extra potting mix, I used soil from the garden that the plant was already used to growing in!

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.

Make over 120 bickies for just $4.00! This fantastic basic bickie recipe is terrific value, makes loads and has lots of room for variations:

500g margarine
1 tin condensed milk
1 cup sugar
5 cups self-raising flour

Cream sugar and margarine. Add condensed milk and flour. Roll into teaspoon sized balls and press down with a fork. Place on greased trays and bake in moderate oven until golden brown (approximately 10-15 minutes).

Before baking I divide the mixture into five and add the following ingredients for different flavoured bickies:
1. Chocolate chips and glace cherries (chopped)
2. Cornflakes and sultanas
3. Hundreds and Thousands
4. Jam drops
5. Milo and coconut

You could add any number of other things like Rice Bubbles, Smarties, nuts, cinnamon and other spices and so on. The raw mixture can be frozen in balls, just thaw slightly before baking.

From this one batch we made 123 bickies and by my calculations using the cheapest possible ingredients, the whole batch cost just over $4.00 to make!

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!

A fantastic and unique gift for under $25 is the 'Useful Box'. It makes an ideal Christmas gift but can be used for any occasion. Basically this comprises of a pretty box which contains lots of those little useful things everyone needs but doesn't always have in one place; such as extra pens, string, Blu-Tac and so on - all the sort of things you want now and again but don't usually have on hand when you need them!

By buying all the supplies at the supermarket and a beautiful gift box at a discount store to present them in, I was able to create an entire Useful Box for just under $25, but you could make it even cheaper depending on where you purchase your supplies. To make it extra special, I wrote a little poem to go with the package! Here is a breakdown of the items I bought and their prices:

Bag of rubber bands - $0.69c
Self-contained sewing kit - $3.98
2-hole pencil sharpener - $0.79c
Paperclips - $0.59c
2-pack of stickytape - $1.19
5-pack of blue pens - $1.99
3-pack of 2B pencils - $1.29
2-pack of erasers - $0.55c
Post-it notes - $0.99c
Permanent marker - $0.83c
Blu-Tac - $1.80
String - $1.99
4-pack of AA batteries - $4.07
Gift box to put it all in - $4.00

TOTAL - $24.75

Other things that might be useful to add include fridge magnets, staples and safety pins. I do recommend keeping everything in its original packaging, to avoid people being stabbed by pins or the erasers getting grubby. Just pop everything in the gift box (including the poem if you wish) and either wrap the box itself up, or simply tie it securely with ribbon.

I printed my poem out and taped it to the underside of the gift box lid, then wrote in the card 'be sure to look under the lid!' You are welcome to use the poem below to make your own 'Useful Box'.

'The Useful Box'

I am a box of useful things,
Gathered from across the land.
Inside me find those things you need
But do not always have on hand.

Next time you scratch your head and think
'I wish I had some Post-it notes'
Just open up my lid and find
The very thing you needed most.

When pencils break or pens run out,
When sticky tape just disappears,
When batteries fail or string is needed,
Let this box allay your fears.

So use me as your Useful Box,
And if you wish please add to me
Those things you like to have on hand
So wanting you need never be!
