Instead of adding up when you do your shopping, why not deduct? This hint explains all.

I no longer use a calculator when I do my grocery shopping. Something to do with always pressing the wrong button and clearing my calculations!

Now, I simply write how much I can spend on my shopping list and when I put something in my shopping cart, I subtract a rounded amount from the total. For example, if I have $100 to spend and I buy milk for $3.89, I subtract $4.00, leaving me a total of $96 to spend on the rest of my groceries.

By making these deductions with every item, you always know how much you have left to spend. Makes it easier to budget and certainly beats using a calculator!

Last Christmas, instead of buying everyone gifts, I bought some small gift boxes for $2.00 each at cheap stores and baked mini puddings and mini rum balls (I made heaps from one recipe), which I put in the boxes. I then tied them with a length of curling ribbon to make them look attractive. Everyone loved the goodies inside, and the maximum cost was $20 for at least six boxes.

I will definitely be doing this again this year. It will probably become a tradition - and why not?

For a super, low-cost, personal and heartfelt gift, why not give someone a Happy Bag? All you need is a plastic 'loot bag' such as those given away at children's birthday parties, and fill with the following:

*An eraser - so that you can make your mistakes disappear.

*Five cents - so you can never say that you're broke.

*A marble - in case someone says you've lost yours.

*A rubber band - to stretch yourself beyond your limits.

*A piece of string - to tie yourself together when things fall apart.

*A bear hug (cut out teddy bear picture or motif) - to remind you that someone cares.

I am a young woman on a single income, paying off my homeloan. I know the amazing financial savings that are possible when you make extra payments of any size on a large loan. However, because I am on a low annual income I often find it very hard to find any spare cash after all the bills have been paid.

So for birthdays and Christmas, when my friends and family are seeking ideas for gifts to give me, instead of asking for things I don't really need, I ask them to deposit the amount that they would have spent on a gift straight on to my homeloan. I am very close with my friends and family and they understand my financial situation. They are only too happy to help me get ahead and hopefully one day own my own home. It is a gift that keeps giving and one I truly appreciate. I read recently that for every extra $1.00 you are able to pay against the principal of your homeloan you will save $2.00 in return and take years off your loan. The understanding and generosity of my friends will help save me tens of thousands in interest over the years.

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!

Christmas 2009 was the worst I ever had, having just separated from my husband. At almost 50 I found myself homeless with no money. On the 16th of December I found a share accommodation but had to borrow money from friends to pay for my bond and two weeks rent so that I could have a roof over my head. The only job I was able to do to keep me going was as a housekeeper, yet I could hardly pay for the petrol to get to work.

For four weeks, I avoided going to the shops. I am 90% vegetarian so decided to grow all the vegetables I like to eat at my rented home. I collected some seeds, seedlings and cuttings from friends and customers and decided to spend my last $10 for chicken wire to protect my homegrown herbs and vegetables from possums and bush turkeys. I am spending time tending my garden every day and I now have lettuces, beans, cucumbers, cherry tomatoes, herbs and so on for salads and stir fries every day. I even have enough to give some to my friends and customers to thank them for helping me to stand on my own feet and living a healthy life. This week I only spent $16 for organic eggs, milk, a tin of pink salmon and a loaf of bread. These with my homegrown herbs and vegetables will give me a healthy diet for the whole week. I am saving heaps to pay my debts as fast as I can.

At soon-to-be-50 and with no savings, I bought The $21 Challenge book to challenge myself. I am so excited because I spent years of feeding a family of four and now I am alone I have absolute control of what I spend and what I put in my mouth. I feel liberated, I feel young and full of energy. Having less money in 2010 is more enjoyable than my stressful life in 2009!

We have saved over $150 in seeds alone this past year. Instead of paying up to $5.00 for packets of seeds which may or may not sprout, we have started grabbing packets of seeds from the herb sections of Woolworths, Coles and IGA. Most mustard, coriander, fennel, cardamom or celery whole seeds that you get as a spice for cooking will sprout for you in your garden. These normally cost around $1.05 per packet and you will get a lot more seeds than if you bought them from a gardening shop. We also get the full dried peas (not freeze dried) from the soup section and have planted these successfully for three years now. They give us the sweetest sugar snap peas ever! A packet normally costs $1.53 and you get close to 100 seeds. In comparison to buy 'packet' seeds it would cost you over $12.

We also cut the ends off shallots and replant them, it takes about three weeks before they start to recover, but then you have an endless harvest of shallot leaves to use in salads. We do the same with old onions that have hidden themselves away in our cupboards and have sprouted. Plant them in your garden, let them go to seed and you will have a great seed stock for the next few years. No need to buy more!

Garlic can be done in the same way. Grab a clove and plant it flat end into the ground. After about four months you will get a great bulb of garlic from your original clove. Be aware that garlic from China or Mexico has been treated with Bromide (cancer causing agent) so only use Australian grown garlic.

Old potatoes and sweet potatoes that start sprouting can be replanted and will give a good yield. Just cut a 3cm piece around the sprouting part of the potato and plant it, from one potato alone you could get up to seven new plants.

Pumpkin, cucumber, capsicum and other vegetable seeds can be cleaned, dried and then planted out to give you more seed stock to play with. Try planting two different types of pumpkins near each other and you might get a hybrid created which tastes great. Our family had a butternut mix with a jap pumpkin and it was the sweetest tasting pumpkin we'd ever tried. We also let one or two of each vegetable go to seed so that next years planting will cost us even less. Our goal is to go totally self sufficient in the garden. So far we have an abundance of butter lettuce, silverbeet, rocket, mint, corn, tomatoes and sugar snap peas all from previously saved seeds.

Protect your personal wallet contents for just a few cents. Just go to your local library and empty your wallet or purse on to the photo copier (license, cards, Medicare - everything!) and make a copy. It can save you hours of worry and extra money should your wallet get lost or stolen. You will have all the numbers and information you need for reference handy - not with the thief!

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.

I’ve saved countless dollars on expensive gourmet ice cream by getting creative with the cheaper varieties. My kids love it when I buy them what they call 'special' ice creams. These are the expensive varieties that come in exotic flavours and cost between $7.00 and $9.00 for a two-litre tub! Needless to say, they really are a rare treat. However, during the school holidays, my kids and I became gourmet ice cream chefs! Using a four-litre tub of Home Brand vanilla ice cream (that cost $4.59), we scooped it out of the tub and let it sit at room temperature for a few minutes. Then we mixed green food colouring, a couple of drops of peppermint essence and some chocolate chips into the softened ice cream to create our very own Mint Choc Chip flavour! We placed it in an airtight container and popped it back in the freezer to enjoy later. The kids were so excited to have made their own special ice cream that we have since concocted many different ‘gourmet’ flavours just by adding ingredients from the pantry.
