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.

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.

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!

I live with my husband and 4 year old twin boys in a unit and we discovered Simple Savings at a time that was very difficult in the life of our family. I wanted to share a bit of our journey that led to saving money and an improvement of our quality of life.

When I discovered Simple Savings my husband was a self employed contractor who was in between jobs and our income became more limited as I work part time and we have many fixed expenses including a large mortgage and preschool fees.

We were feeling very stressed emotionally as well and finding daily living difficult to manage. I pored over the Savings Vault and found a wealth of information so assist us in reducing our expenses. As we were feeling quite vulnerable and finding change a struggle we picked one tip a week to research or implement and we started with the simplest first so we could experience enough success to motivate us to continue.

So the first week my husband put his razor in a small glass of olive oil (to prevent rust and make the blade last longer). Then we replaced our fabric softner with 1/4 cup of vinegar and put vinegar in a pump spray pack to clean our benches. We also used vinegar to clean our floors. As we "succeeded" we began to feel better about life as we were exercising the control we could to improve our situation and it felt creative.

We also:

Researched car/house/contents insurance for the best deal

Started to shop at Aldi regularly, knowing from other Simple Savings users which were the best value products

We found a wholesale butcher (Elvy's Wholesale Meats 2/19 Norman St, Peakhurst tel: 9153 6656)

We started cleaning our dishwasher with citric acid

We gave homemade gingerbread houses and biscuits as Christmas gifts

Our children made gift wrap (painted and glittered) from a roll of butchers paper bought for $10 at IKEA which is very personal and inexpensive.

We joined 3 different DVD clubs and got a free month from each before cancelling which gave us great free entertainment over the Christmas months.

We found websites for children's activites, and a recipe for homemade playdoh that we love and have given to other children as gifts.

We also bought $8 worth of alphabet and flower beads and bracelet elastic from The Reject Shop and made 13 name bracelets for preschool teachers and friends. My boys really knew the joy of giving something that they had helped choose and make. The recipients were joyous at the personal nature of the gift.

I now make my own bath products for our family and for gifts from the recipes and websites reccommended by Simple Savings subscribers.

We are adding to our life routine regularly and we are loving our life. This week I have taken my first week of unpaid leave from work to be with my cherubs during the school holidays and it is such a priceless and precious gift.

I really appreciate the invaluable life tools that I have gained from your website and value sharing this way of life with my children. And I encourage the overwhelmed to add one tip a week to your life...they all add up to big change.

We decided to get rid of the $96,000 mortgage on our home within three years. The massive load of interest we would pay to the bank was over the top and we felt that the bank owned us. The entire family bought into the project one hundred percent.

1) We replaced the nice modern cars with older, less costly ones. The net difference and any savings we had and $700 from a garage sale were paid off the mortgage.

2) We agreed to budget as if we were in a life and death war and the war had to be won in three years. I developed an Excel budget spreadsheet and we tweaked the numbers until we had a 'do-able' weekly saving of $220 extra to pay off the mortgage. Clothes purchases would be done exclusively at 'Harrods', our Salvation Army shop, until the war was over.

We decided to run any item not budgeted for over three 'hurdles'.

The first hurdle was 'could it shorten the mortgage war?'

The second hurdle was 'is it a health issue?' and if so what was the least-cost workable solution?

The third hurdle was 'could it wait until the end of the three years?'

3) As time progressed we became pretty smart at reassigning money to reward ourselves for enduring the war. This meant we could have a low cost take away sometimes, or spend on an out of budget item we had set our hearts on.

It took nearly four years to knock off the mortgage. Yes, we won the war a little later than hoped, but we won. If it had taken eight or nine years to win, it would still have been worth it.

The legacy of our war against the mortgage is that we have developed great money saving skills for life. And life is great.

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!

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

For many people juggling work, family and study, time is the most important saving they can make. I work four days a week, have a three-year-old and studied part-time for a diploma for a year. I got by with these time-saving tips:

1. Lowering my expectations for the house. I don't need a spotless house, but a tidy and lived-in home.

2. Doing my housework little and often, rather than spending huge amounts of time tidying up. I do things like:

- put my little one's daycare bag together for the next day as soon as we get home in the afternoon.
- cook my lunches (pasta and sauce, muffins and so on) once a week and freeze them.
- put my lunch box together from the freezer in the evening.
- clean the toilet by putting a teaspoon of Napisan in it each night. It soaks overnight and the bowl is clean with the next flush.
- do laundry when enough for a load accumulates so we don't have a sudden clothes drought, then an avalanche of laundry to do and put away.

3. Exercising on a stationary bike in front of the TV in the evenings after my little one is in bed.

4. Programming our DVD recorder once a week (Sundays when we get the new TV guide) so I don't miss my favourite shows.

5. Filling cereal bowls with water if I am rushing and have to leave the breakfast things. This makes them easier to clean later and stops ants.

6. Trying not to double handle things. Rubbish goes straight in the bin, meat is put in meal size portions in plastic bags and frozen as soon as it gets home, magazine subscriptions go straight to magazine rack when they arrive in mail.

7. Leaving rooms better than when I arrived, so the need to tidy doesn't build up. It only takes five minutes to put laundry from the floor to the hamper, make the bed, wipe a bench, replenish the toilet paper.

8. Recruiting my little one to help - she's only three but she can put dirty dishes in the sink, put toys away in her room, dirty clothes in the hamper.

9. Shopping for groceries by myself in the evening so hubby can watch his TV shows in peace and I am not tempted to go to other stores as only the supermarket is open. Also many things are marked down at that time.

10. Trying to do three things for myself that make me feel happy each day, like listen to podcasts while I do the housework.

11. Writing the shopping list progressively through the week so I can pick it up and go when it's time to do groceries.

12. Storing the bedding in storage containers under each bed so it's quick to make the bed, especially when changing my little one's wet sheets in the middle of the night.

13. Shopping for presents at sales during the year (online or in stores) so I don't need to go to crowded stores during the Christmas rush.

14. Not beating myself up if I find lifestyle changes tricky at first - I am afterall human!

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.
