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.

I have slashed my grocery bill, kept my kids from grazing AND lost five kilos, simply by enjoying a bigger breakfast. Breakfast items are generally cheaper if you are careful how you shop. Plain brand muesli, Vita Brits, porridge and cornflakes are all cheap items to have in your pantry. Plain brand yoghurt, fruit (canned or fresh) and vegetables are also fairly cheap, as well as tuna on toast. The helpings are generous and we eat until we are full. I've found that over the course of the day, hunger pains are gone, snacking is unnecessary and we eat smaller portions for lunch and dinner. Our savings have been made especially on dinner; we find that we don't eat as much meat and it takes a lot less to satisfy us at night. Not only have the kids stopped grazing, they have better concentration at school, eat all of their dinner because its a smaller portion and have stopped that afternoon dash for sugar, chips and treats. The kids enjoy eating the bigger breakfast because they are really hungry in the morning, as opposed to eating a heavier meal at night when they are tired and fussy and likely not to eat much. Since changing our biggest meal from dinner to breakfast, I've lost five kilos in four weeks and our grocery bill has gone down by at least $30 a week. I can also bulk cook dinner and make them stretch even further now. I look and feel great, am saving money and my family is happier too!

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.

People are constantly amazed when we tell them that we have managed to whittle down our weekly grocery bill to just $100 for our family of four. Our income may not be all that we would wish, but with a little dedication, we have made a huge difference.

For example, in recent months, we have saved $50 per week on our grocery bill, since we have started throwing away our supermarket circulars! For years, I eagerly awaited the arrival each Sunday of the supermarket 'junk' mail. I would plan our eating to a large extent on the weekly specials, and would stock up on a few of them, believing it was saving me money.

However, once I began throwing them away without even a glance, it had an unbelievable effect! Not only did it cut down on the clutter in the house, but amazingly my grocery bill plummeted. I now buy only what I need - as opposed to what the stores want me to buy - and the benefit is showing. By throwing out the junk mail alone, our weekly grocery shop reduced from $150 per week to around $100, saving $2,600 per year!

I still use a menu plan to help me stick to my budget, but now it is food of my choice, rather than being influenced by supermarket advertising. A typical weekly menu might look like:

Monday - Baked chicken and salad (whole chicken $2.50 from local butcher)
Tuesday - Fish and chips (fish $2.00 per pack at ALDI, I use potato gems or
chips about $2.00)
Wednesday - Pasta bake & salad
Thursday - Taco's
Friday - Baked beans (ALDI's are really cheap at around $0.40c for two cans)
Saturday - Chicken legs, pasta and salad (chicken legs $2.00 per kilo)
Sunday - Quiche & salad

I usually have all the meat I need already available, as I buy in bulk, so all I need to buy for the week are any other items to complete the meals. I buy salads and vegetables on alternate weeks - one week we have salad with everything, the next week I buy vegetables for all our meals. It may sound an unusual way of shopping, but this way there is no wastage; unlike when I used to buy both.

I don’t buy everything in bulk, but some items work out more economical, such as:
Bread - I buy bread from Coles after 6pm to take advantage of the markdowns - for example, $0.50c for a packet of bread rolls, or a loaf of bread.
Chickens - Patton’s, our local butcher have many great specials, including chickens for $2.50 each. I buy ten at a time and freeze them; they may not be huge, but plenty enough for a family meal, plus leftovers for sandwiches.
Fish - ALDI have oven bake fish for $2.00 per packet (the cheaper of the two
versions). They are like large fish fingers, and perfect for us. Combined
with the chips or potato gems, the whole meal for a family of four comes to $4.00.
This is a standard meal for us, and I make sure I buy plenty to last between ALDI visits. Ice cream - I wait for special offers so I can purchase five litres for $5.00 and buy in bulk.
It also pays to buy washing powder and toilet paper in bulk when on special, as they don't go off and you will always need them!

When I was planning my meals around the supermarket brochures, my shopping list was actually doubling - that was without any impulse buying as well! Another thing I also now do to cut down costs, is alternate a meat meal, with a non-meat meal. You will see from the menu plan above how we eat meat and vegetables one night, baked beans the next, or pasta bake and so on. We enjoy our meat, but find we can cope with every second meal being meat based, and it really keeps costs down.

We don’t eat cereal every day for breakfast, it works out too expensive - it’s actually more expensive to eat than steak! We have toast, eggs or grilled tomatoes. With the children, lunches are mainly sandwiches; the kids like their Vegemite, peanut butter and Nutella; the adults make use of any leftover meat. For school lunches, I dropped most of the expensive packaged goods (for example, Rollups) in favour of two sandwiches and a piece of fruit. They still have a lunchbox treat now and then, but it’s sometimes, not everyday.

One tip I have learned which has really helped me is that the family actually prefers me to cook from their range of ‘family favourites’, rather than consulting cookbooks or fancy magazines. If this is what they enjoy - stick to it and save yourself the time and money!

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.

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.

Sometimes I feel as though I've lived on a budget all my life! I live alone in a second floor rented apartment - no yard or garden, just a concrete car park. To combat that 'locked in' feeling, I have endeavoured to bring the outside in for little cost.

I have several indoor plants; beautiful, green and healthy. My small cold water fish tank has two goldfish in it, they are healthy and lively and provide colour and movement darting around. Very cheap pets too, a can of fish food lasts for ages and you can get all kinds of tanks to suit any budget.

I conserve water by using the 'old' water from the fish tank when I change it to water my plants, giving them lots of nutrients! I also use the water left from steaming vegetables to water the plants too.

I have no car, so must walk to get my groceries and other needs. I tell myself this is all POSITIVE. Everytime I walk to the shops and back it is exercise and energy sustainable. I'm not creating any air pollution either!

Almost all my clothing comes from the local opportunity shops - guess you could call me Second Hand Rose! I have three good op shops in my area, which are also great for cheap books, kids' toys - just about anything you can think of!

Frugality is not about being 'mean'; it's often very necessary for those on a fixed and limited income - and it can be a lot of fun!

Watching my 'non-Simple Savings' sister unpack her groceries this week made me realise how much my shopping habits have changed in the year since I discovered Simple Savings. I used to love supermarket shopping, wandering the aisles for hours, one of this, one of that.

Some products I just don't buy anymore include:

• Liquid handsoap - I now make my own (my first SS project from the Vault). Saves $40/year.

• Spray and cooking oil - I buy 4L of good olive oil on special for about $20 and use a refillable hand pumped spray container (from House, $15 - will last years). I used to buy cans of olive oil spray at about $3.50 each and by changing how I buy oil, I am saving $100 per year.

• Cleaning products - are now missing from my list - we use bi-carb and vinegar and other simple Vault tips.

• Dishwashing cleaner - has gone too. We use citric acid, which I normally keep for my yearly lemon cordial making.

• Soft drinks and cordials - are rarely bought now - we use juice as you would cordial, and have changed our habits in favour of water.

• Yoghurt - we make EasiYo using packets bought in bulk from GoldenGlow online. Saves about $150 a year.

• Eggs and vegies - in the back yard!

• Condensed milk, Yogo, cake and pancake mixes - we M.O.O. ('make our own') using Vault tips.

• Icypoles - M.O.O. using tinned fruit juice or other - search the Vault!

• Magazines - I never buy new, just pick up the free supermarket recipe brochures or occasionally buy some gardening ones from the op shop.

• Junk and pre-prepared foods - we buy a lot less in favour of having our own 'sausage roll make-athons' or other baking with the kids.

As well as noticing the presence of many of the above things in my sister's shopping, I also noticed she buys small quantities of lots of items I now buy in bulk. Each week she has to mentally or physically check if she 'needs another of...', where I buy large amounts from the supermarket and other cheaper sources - and then don't need to think about it again for at least six months. These types of products include:

Washing powder (I'll never buy less than 20kg, and with the Vault advice to reduce our amount per load, this is lasting ages!), teabags, coffee, shampoo, dog and chook food (from pet supplier every six months), ham and meats(buy large piece of ham and store in ham bag per Vault tip - saves at least $50 a year over my previous habit of buying little cute packets of 50g each), bacon (buy from ALDI and freeze), dishwashing powder (ALDI brand is MUCH cheaper than the Finish tablets we were using - saves us $150 a year at least. I buy 12 months supply on one of my ALDI runs), cheese (buy larger amounts less often and freeze if necessary), rice (10kg bag much cheaper), jelly crystals (I bought 5kg bag at IGA last week - makes 20 serves for same cost as three individual packets), tinned fruit, soup, tomatoes and other products (from SPC outlet), nappies, paper towel and toilet paper (I buy lots when on a fabulous special). Fruit and veg I buy from the greengrocer, the market or grow my own. Meat is from the butcher, chicken from the poultry shop and fish from the fishmonger once every three months.

I could go on for every grocery item - nearly everything has changed in 12 months. This is even without noting the savings from changing products - for example, I used to think myself very clever if I bought my Uncle Toby's quick oats on super special for $2.00 per kg box - until I discovered I can buy Home Brand, which I cannot fault, for $1.00 a kilo all the time. Same for most basic products.

With changes like these to my grocery shop and to our home loan, insurance, shopping habits and so on, Simple Savings has saved us thousands of dollars in our first year of membership. Our lifestyle has actually been RICHER since SS. I didn't set out to change my shopping habits - I just started by making handsoap and buying Home Brand porridge oats - but suddenly I have realised how large this change has been. If I see you at the supermarket with your milk, bread, 8 large packets of toilet paper, 6kg of the super special meat, 10kg of rice and three-litre containers of vinegar, I'll know you caught the bug too!

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.

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!
