To help me stick to my budget, I use the 'purse system', where I allocate a certain amount of money each payday to pay for different things, for example, petrol or groceries.

I found the envelope system aesthetically unappealing and difficult to operate, so I purchased a number of small pencil cases from Office Works; they're the perfect size to fit dollar notes into and any receipts for that particular 'budget purse'. I have a red case containing money for my groceries, a black case for my petrol and so on. They are also attractive enough that I use them as my wallets for these purposes; unlike envelopes, I am never too embarrassed to pull a case out and carry it into a shop. The cases cost $8.00 each but they motivate me to stick to a budget - a huge long-term saving!

Hard glasses cases are a great, cheap storage solution. I was looking for something to carry my make-up in for the holidays and my old hard case was perfect. It fitted everything I needed and the hard cover prevented any breakages. You also avoid the hassle of tipping out a soft make-up bag to find what you need! I then put the loose things in my glove box (screwdriver, scissors and pen) in another hard case and made myself a travelling tool kit. You could use them to store miniature sewing kits when travelling and much more. These cases are cheap to buy in second hand shops, and many are nicely decorated or you could do this yourself.

I have finally convinced my three daughters that eating a healthy lunch, including sandwiches with salad, is not only good for them but tastes great too. However, soon after changing their lunch habits, I found that this method was taking a large chunk out of our budget.

Being a working mum, it was easier to stop at the supermarket on the way home and buy pre-packed salad ingredients, but I soon discovered it was adding around $55 to the weekly budget. Plus, buying cold meat to match everyone's tastes added another $40 per week. I decided it was time to cut down. After doing some homework looking for the best prices and quality, I now purchase a bag of carrots, a couple of fresh beetroot, some fresh bean sprouts and cucumbers and a variety of lettuce. I noticed that by purchasing these items late on Sunday afternoon, I can pick them up even cheaper.

I grate my own carrot, beetroot and cucumber, throw in the bean sprouts and store in the fridge in an airtight container. I tear up the lettuce leaves and mix together in a plastic shopping bag and store in the vegetable crisper where they stay fresh and crunchy all week. My salad ingredients now cost less than $10 per week and they last longer. Throw in a small portion of sundried tomatoes for my hubby and I add approx another $1.50 to my total.

Instead of buying cold meat from the supermarket deli, I now purchase a couple of extra chicken breast fillets from my Asian butchery for around $4.00; this is cheaper than ALDI or any other local fresh meat source. I cook and shred the chicken myself while tinned salmon and tuna add extra variety; a $0.69c tin of tuna covers two lunches when added to salad. I purchase mince when it is on special and make a large batch of meatballs, which are frozen and used over a period of weeks as another filling alternative. Another favourite is home cooked corn beef; rather than putting the leftovers in the fridge, I slice it thinly and freeze for another filling choice.

My three girls are now involved in the Sunday afternoon preparations. Whilst my eldest daughter is madly grating the salad items, I tear up the lettuce and my younger daughters have great fun mixing the meatball ingredients and rolling them ready to cook.

Our family of five is still eating yummy healthy lunches but for $70 to $75 a week less than before!
We also have the added bonus of spending time together while we prepare and my daughters are learning new skills too.

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.

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

I make these Cheesy Ham and Corn muffins, which are delicious and at only $0.44 each to make, give me and my family something tasty, cheap and healthy in our lunchboxes. They are yummy cold, or heated up in the microwave.

Makes 12

Ingredients:
1 x 310g can of corn (reserve can for measuring)
½ cup reduced fat milk (1/2 ‘can’)
2 eggs
2 cups of self raising flour - I use wholemeal (2 ‘cans’)
Pinch of salt
2 cups reduced fat grated Australian cheese (2 ‘cans’)
2 slices ham, cut into strips
2 teaspoons English mustard

Method:

Whisk together corn, milk and eggs in a large bowl until combined. Add remaining ingredients and stir until just combined.
Spoon mixture into non-stick ½ cup muffin tray.
Bake at 200c for 15-20 minutes or until golden brown and cooked through.

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!

I found a way to save almost $50 a year on liquid hand soap with hardly any effort! Just take a bucket filled with four litres of water. Drop a bar of generic soap into it and let it soak for 24 hours. Give it a mix and pour into clean two-litre milk bottles. Just top up pump bottles when needed. For a little added luxury, add half a cup of sorbolene cream and a few drops of glycerine. Works a treat!

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 add a supermarket gift card to my weekly grocery list and use them all up to shop for Christmas! After doing some calculations I realised that the ready-made Christmas hampers that you pay for weekly cost three times their actual value, not to mention the fact that they can include many products you won't ever use. My new system for buying Christmas groceries lets me buy my own hamper full of items at the current price or on special.
