We've saved at least $10,000 this year alone, simply by changing our shopping habits!
 
Almost every day, we'd stop at the supermarket on our way home to buy fresh ingredients for dinner – however, we'd also buy a couple of impulse items while there. The daily grocery bill was at least $30; an extra $150 each week on top of our weekly 'big' grocery shop!
 
To reduce the number of trips we made to the supermarket, we analysed our spending habits. We looked at all the grocery items we purchased and separated them into three categories:
 
1. Perishable items that need to be used within a week or so, for example, milk, bread and vegetables.
 
2. Items that had a longer shelf life or could be stored so they last longer, for example, meat that could be frozen, canned items, pasta and rice.
 
3. Items with an extended shelf-life such as toilet paper, detergent, toothbrushes and so on. We then estimated how much of each item we would use in a year.
 
We looked at what we could make or grow ourselves, for example, bread baked in the oven or herbs and vegetables grown in the garden. That left a limited number of items we needed to buy on a weekly basis including milk, fruit and vegetables; at least until the garden was established. These were all items we could buy from the local fresh food market, avoiding a trip to the supermarket, which meant lower prices and fewer impulse buys.
 
The next step was to develop a monthly meal planner - five meals per week with two nights of leftovers or 'invention' cooking using whatever was in the fridge, freezer and cupboard. We put all the recipes in a folder and worked out a monthly shopping list based on these recipes. All non-perishable ingredients are now purchased in this monthly shop. Meat is also purchased monthly from a butcher who offers bulk purchase discounts; the meat is frozen in meal lots ready to be thawed in advance for each meal.
 
We don't tend to cook in bulk, as we enjoy the process of creating fresh meals each day, but we do cook enough to provide the next day's lunch and occasionally cook a couple of casseroles or 'one pot' dishes at the same time and put them in the fridge - the flavour seems to build and is even nicer after a day or two.
 
Our menus also change depending on the season and what produce is available at that time. We're in the process of developing 'summer', 'autumn', 'winter' and 'spring' meal plans with enough recipes to get us through each season.
 
Finally, during each monthly shop we'd buy extended shelf-life items when they were on special until we had a year's worth. It takes up some extra cupboard space but we never run out of essentials and don't have to duck out to the supermarket.
 
Our ultimate goal is to reduce our 'big' shops to once a quarter rather than monthly – this will save us even more time and money by further reducing our exposure to the supermarket.
 
We have saved $150 a week by eliminating daily shops – this adds up to $7800 annually. We've saved even more by shopping at fruit wholesalers and butchers, buying in bulk or taking advantage of specials. By changing our shopping habits, we estimate we've saved at least $10,000 this year!

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 pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

Skint but stylish. That's how I like to think of my lifestyle, because it is such fun to live on the smell of an oily rag without anyone else knowing! Eighteen months ago, although in recovery from depression, I found myself many thousands of dollars in debt and with several accounts having been sent to collection agencies. I was also 31kg overweight and at risk of cardiovascular disease and Type 2 diabetes. The excess weight (not to mention the stress!) was also making my arthritis worse. I was no longer able to work in my former profession and, as I was in my early sixties, I wasn't able to find other work and was on Centrelink (Social Security) benefits. I have since been transferred to the Age Pension. I knew I had to make some drastic changes, and pretty darn quickly too! I had just a few things going for me:

• My Visa card was a debit, not credit, card.

• My account was with a credit union, rather than a bank, and fees are much less.

• I was knowledgeable about nutrition.

• I was willing to face unpalatable facts about myself and make lifestyle changes.

With this small armoury, I prepared to do battle! The first thing I did was to sit down with all the paperwork, and list all the accounts, personal loans and the total. I nearly had a heart attack right there and then, but with the information, I was able to draw up a projected payments schedule. I contacted all the collection agencies and told them how much I proposed to pay each fortnight until all were paid. I did the same with private lenders. Nobody turned my proposal down; it really is true that, if you get in contact and show willingness, most lenders will give you time to pay. They would rather have their money than you in jail!

Step 2 was to organise payment of my electricity account by direct debit from my pension - what you never have, you never miss. Once the phone bill was paid off and reconnected, I did the same with that too. In all, my debt reduction program was going to be about $200 per fortnight, or roughly 34% of my pension and Centrelink allowances. Since my rent costs another 34%, the remaining 32% had to stretch to cover food, cleaning materials, clothing, pharmacy costs over the pharmacy allowance, fares for trips outside walking distance, presents, postage, life insurance and credit union fees (direct debit from my credit union account), occasional small charitable donations and the occasional small treat.

Step 3 was to go on to a sensible eating program (not a fad diet) that would help me to lose weight, bring my blood glucose and serum cholesterol levels into the normal range. A low GI, high carbohydrate, moderate protein, low-fat pattern fitted the bill in all respects. The challenge was: could I do it on $50-$75 per fortnight? The answer is yes! I make my own wholemeal bread, soups, skim milk yoghurt and lots of interesting dishes from many countries, based on grains and vegetable proteins, and stock up on tinned oily fish for essential fatty acids when on special. I have red meat and poultry only once or twice a fortnight and the rest of the time my proteins are derived from legumes, eggs and low-fat cheeses. It's just as well that I like oats! I drink two litres of water a day and make my own herbal teas from homegrown herbs. I don't buy soft drinks and buy leaf tea rather than tea bags, as it's better value per unit serving. I find whole fruit better all round than juice as a rule.

Step 4 was to get mobile! I walk, because I can't afford gym membership, and walking can be done by those who can't jog. Being out in the open air blows away the blues too. Having won a free pedometer, I wear it and try to reach 10,000 paces a day. I also started a vegetable garden and this saves me money where it counts, on vegetables, as well as being another source of fresh air and exercise.

Is it working? Is it what! In the last financial year I paid off $5000 in debts on the pension alone, and am on track to achieve the same amount this financial year. I lost 13kg in the same period - a nice, sustainable rate. My blood glucose level is normal, my serum cholesterol almost so, although because of familial hypercholesteraemia, I need some medication to help with that. I am continuing to lose weight slowly but surely and have much more endurance and less pain. My GP is nearly as stoked as I am. I take care of my clothes, believing that 'well-pressed is well-dressed', so my appearance doesn't give me away either. Occasionally I earn a little money from magazine contributions and this usually goes towards seeds or something else for the garden, but occasionally I restock the pantry with staples. I make my own cleaning products with such simple substances as vinegar, bi-carb of soda, washing soda crystals, soap scraps, eucalyptus oil and - wait for it - Worcestershire sauce (cleans brass and copper a treat, and one nearly always has it handy). I turn my appliances (apart from the fridge) off at the wall when not in use and have noticed a difference in my power usage. All my incandescent light bulbs have been replaced with long-life fluorescent ones, and by crafty use of acrylic-lined curtains I keep my house cooler in summer and warmer in winter. I pile on the clothing layers in winter and wear cool clothing in summer. If I'm watching TV in the winter, I cover my legs with a woollen rug and put on another cardigan if necessary, rather than turn up the heater.

Because I can't afford much for presents, I give of myself. A nice present is a 'book of vouchers', made attractively and containing such redeemable coupons as: 'This voucher is good for two hours' ironing... or an evening's baby-sitting... or... whatever!' Very few people say no to home-made goodies either. It makes me feel truly wealthy to give someone a loaf of bread still warm and fragrant from the oven, or a jar of chutney.

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!

As school has gone back, and exercise books need covering, I thought I'd share this money and time saving tip.

I bought a box of 100 plastic sleeves, just like the ones you clip into ring binders. These cost me just $1.50. I then cut off the spine and the bottom of each sleeve, leaving me with a piece of plastic that is the perfect size for covering exercise books. The spine of the book fits and holds neatly in the crease, and the overhang is the perfect width for folding over the edge and sticking down. So simple, and at $1.50 to cover 100 books, so economical too.

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.

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.

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.
