I can make hundreds of litres of liquid plant food from just $12 worth of Dynamic Lifter pellets! This will buy a 10kg bag. Just add around four handfuls of pellets to a nine litre bucket of water and let steep for a couple of days, mixing occasionally. When you have a nice 'tea', pour a couple of litres of the liquid, into a nine litre watering can, top up with water and give your garden a drink. Repeat until all the 'tea' is gone, then add more water to the residual at the bottom of the bucket and repeat this process. As the mixture gets weaker, you can use on seedlings, vegetables and more delicate plants such as azaleas and gardenias. The 'weak' mixture can be used as a health tonic or sprayed directly onto the foliage of plants (remember not to spray if the weather is over 20 degrees Celsius, as this will burn the foliage). Once you get to the real weak stuff, simply pour the residual under a tree and water in well.

You can also make hundreds of litres of liquid fertiliser from a 10kg bag of Blood and Bone pellets at an initial cost of approxiamtely $1.20 per kilo. Compared to a litre bottle of liquid plant food (such as Seasol) which costs about $10 and will make just over 300 nine litre buckets (going on the manufacturer's average of 30ml per bucket), your bag will make many hundreds of buckets of first grade solution followed by many more second and third grade 'weak' solutions which are ideal for foliar feeding. A huge saving, which will give you enough fertiliser to last you a whole year or more!

Simple Savings has become a way of life. I don't have to think about saving or spending now - it just comes naturally. In the past five and a half years, we have managed to pay a whopping $150,000 (principal) plus interest off our mortgage and still live happily and comfortably. This is all due to Simple Savings.

My husband and I have three young children and our combined income is only average, ranging between $50,000 - $70,000 per year. Readers may think 'I could never do that, I would have to go without too much' or 'that's impossible', but this is not true. We don't go without; in fact we feel we do pretty well! I cannot name just one single thing that has helped us to achieve this and still be happy - it is a multitude of tips and hints, all of which can be found on your site. I have always been a Simple Saver, so for me this was not hard, but my husband found not being able to spend money willy-nilly difficult at first. These days, I am proud to say he thinks before he spends and at times even proudly tells me of his smart purchase or why he didn't purchase!

I could go on and on giving examples on how to do what we have done, where we saved money and how we used it more wisely, but that would make a book and to be honest all people have to do is log on to your site, it's all there. Focus on your goals, walk hand in hand with Simple Savings and your dreams can come true.

A few simple lifestyle changes have helped me lose 26.5kg AND slash my food bill by $35 a week! Over the past six months I have developed my own healthy eating and exercise regime. I began by pushing my one-year-old for an hour a day to the park and around the shops at a brisk pace, using our $20 eBay running pram. I also invested in some second hand hand weights and after extensive research on the Internet, I started my own regime of weight training exercises.

Food-wise, I began buying in bulk and made my own nutritious meals, rather than relying on 'ready to eat' microwave health meals. This way I knew exactly what was in each meal and there was never any waste. I started making my own meal plans and eating smaller portions, going from a 3000 calorie-a-day diet to 1500-1600 calories per day.

Under my new regime I soon began to lose the weight, but the real bonus for me has been in the savings I have made. Changing the way I ate and my portion size has resulted in me saving $35 a week over the past 26 weeks! A win-win situation all round. No personal trainers, fancy diet shakes, pills or supplements - I simply used what I had. I feel fantastic and have the energy levels of a teenager! If I can do it, anyone can!

My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

During my uni student years I developed a menu-planning and grocery shopping system that allowed me the freedom to eat well, generously fuel my bicycle-based lifestyle, entertain guests regularly and experiment with new recipes, all within my strict food budget of just $15 a week!

It works like this.

1. Decide how much you will spend on your weekly groceries. In recent years I have had to increase my spending to about $21 a week due to rising food costs and CPI, but the system still works really well when I use it and is a great way to separate needs from wants.

2. Choose the staples and basics that are to be made every week as needed. These could include soy milk, tofu, sourdough bread, yoghurt, sprouts, hummus, fresh lemon cordial, Anzac bickies, gomasio or whatever else you require.

3. Give the ingredients needed to make these staples first priority when making the weekly shopping list. If you have a local food co-op you can buy mostly organic ingredients with minimal packaging in exactly the amounts you need.

4. Check what else is in the fridge, cupboard, garden or neighbours' garden and pore over your large collection of second-hand recipe books to see what can be created with these other ingredients. Recipes which require two or less extra (and inexpensive) ingredients are preferred and a list of these and their corresponding cookbooks/page numbers is made and stuck on the fridge. There will usually be a selection of mains, side dishes, desserts, treats and beverages on the list.

5. Give the extra ingredients needed for the chosen recipes next priority on the shopping list. Over time you will intuitively know when your shopping list is 'full'.

6. Once out shopping, specials of the day such as a big bag of discounted apples or cheap cooking tomatoes take third priority. If not consumed within the week, these can form the basis of recipes chosen for the following week.

7. Last priority (and usually only considered after the register shows you are still under budget) are those inevitable temptations that one wants rather than needs. It often helps me to take my recipe list with me and remind myself that I can make a delicious self-saucing carob pudding at home for a fraction of the cost of the tiny chocolate bar I am now contemplating. All of a sudden the money seems much better spent on a kilo of brown rice!

8. Back at home, simply cross the recipes off the list as they are made. There will always be plenty of food for dinner parties or last-minute guests, and the sometimes tiresome decision of 'what to cook?' becomes easy.

Using this system I have never run out of food or felt like there was 'nothing to eat'. In contrast, I have stayed at many houses where, despite having pantries and fridges which are bursting with food, the occupants have driven to the supermarket and easily spent $30 or $40 just to cook up dinner for the night.

Seems unbelievable? Try scratching every processed food item off your own shopping list and see how many more kilos of real food you can come home with for the same amount of money. Don't forget too, to keep an eye out for trees in public areas which are loaded with fruit or nuts. I have used the $15 a week food budget for stretches of up to a year at a time, which means I certainly wasn't relying on stockpiles of food from more extravagant days tiding me over. Necessity breeds creativity, and I am so happy to have been forced early on to examine and separate my wants from my needs in this regard. Even when times are tough, I know I can eat well!

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 am saving around $100 a month on my grocery bills, thanks to a few simple changes to our family meals. I wanted to reduce our food bill and after some thought came up with the idea of making two nights per week a '$2 Dinner Night'. For example, one night we will have something like toasted baked bean sandwiches or stuffed baked potatoes; the other I use up all the leftover vegetables in the fridge to make a self-crusting quiche. This reduces the amount of food we waste and the kids love it. Even the simplest meals can be delicious and filling and the savings we are making from our twice-weekly $2 dinners are well worth it!

Saving $1.00 a day has helped me afford things I would have otherwise struggled to pay for. I started doing this when my sons started at a private school in the city. They would be invited to several birthday parties throughout the year, so to ease the financial burden of gift giving I used my money box. At the end of the year I would use whatever was left to buy school supplies for the following year.

My children have left school now but I still save my $1.00 a day which I use to treat myself to a pedicure, go to a movie or have coffee with friends. It's such a small amount each day that I find it doesn't really affect my household budget, but it always came to my rescue when I needed it, and now affords me my treats.

I have been receiving your fabulous emails for ages and I thought I'd share a favourite saving hint of my own.
 
My naturopath gave me a tip which saves money and is better for our health too. She said that most hand sanitisers contain chemicals and antibacterial properties that not only kill bad bacteria but also kill off essential good bacteria. The good bacteria on our hands helps to fight off infections and acts as a barrier, so hand sanitisers can compromise our ability to protect ourselves.
 
My naturopath gave me a natural alternative. She told me to buy some small atomisers and a bottle of water-soluble tea tree oil from the chemist. I would then pour about 20 drops of oil into each atomiser, and fill with water – that's all it takes to make your very own antiseptic.
 
These natural sanitisers are cheap, effective and have a lovely scent. An atomiser easily fits into a handbag, and is very handy if the kids get scratches and scrapes after playing – a quick spray on the affected area is all it takes.
 
Tea tree oil really is the best antiseptic around and there are so many uses for it. Happy natural sanitising!

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.
