I grow most of our vegetables to eat healthy and save money. I save all scraps to compost and I wanted a tumble composter. They turn lawn clippings and scraps into compost in 14 to 21 days. The composter is priced at $410. I bought a 240 litre plastic drum (cherry bin) from the local trash and treasure market for $5.00. My husband drilled holes in the lid. It doesn't have a frame but I roll it on the lawn for five rotations once a day and I make compost in 21 days. It isn't hard to roll but I can't empty it into a wheel barrow (I'm only five feet tall) so I spread a sheet of plastic on the lawn and tip it out onto that. The compost is fantastic.

For many people juggling work, family and study, time is the most important saving they can make. I work four days a week, have a three-year-old and studied part-time for a diploma for a year. I got by with these time-saving tips:

1. Lowering my expectations for the house. I don't need a spotless house, but a tidy and lived-in home.

2. Doing my housework little and often, rather than spending huge amounts of time tidying up. I do things like:

- put my little one's daycare bag together for the next day as soon as we get home in the afternoon.
- cook my lunches (pasta and sauce, muffins and so on) once a week and freeze them.
- put my lunch box together from the freezer in the evening.
- clean the toilet by putting a teaspoon of Napisan in it each night. It soaks overnight and the bowl is clean with the next flush.
- do laundry when enough for a load accumulates so we don't have a sudden clothes drought, then an avalanche of laundry to do and put away.

3. Exercising on a stationary bike in front of the TV in the evenings after my little one is in bed.

4. Programming our DVD recorder once a week (Sundays when we get the new TV guide) so I don't miss my favourite shows.

5. Filling cereal bowls with water if I am rushing and have to leave the breakfast things. This makes them easier to clean later and stops ants.

6. Trying not to double handle things. Rubbish goes straight in the bin, meat is put in meal size portions in plastic bags and frozen as soon as it gets home, magazine subscriptions go straight to magazine rack when they arrive in mail.

7. Leaving rooms better than when I arrived, so the need to tidy doesn't build up. It only takes five minutes to put laundry from the floor to the hamper, make the bed, wipe a bench, replenish the toilet paper.

8. Recruiting my little one to help - she's only three but she can put dirty dishes in the sink, put toys away in her room, dirty clothes in the hamper.

9. Shopping for groceries by myself in the evening so hubby can watch his TV shows in peace and I am not tempted to go to other stores as only the supermarket is open. Also many things are marked down at that time.

10. Trying to do three things for myself that make me feel happy each day, like listen to podcasts while I do the housework.

11. Writing the shopping list progressively through the week so I can pick it up and go when it's time to do groceries.

12. Storing the bedding in storage containers under each bed so it's quick to make the bed, especially when changing my little one's wet sheets in the middle of the night.

13. Shopping for presents at sales during the year (online or in stores) so I don't need to go to crowded stores during the Christmas rush.

14. Not beating myself up if I find lifestyle changes tricky at first - I am afterall human!

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

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.

My husband and I are soon to become parents and our income has been cut in half. Now that we're on a tighter budget, I have realised how much we were caving in to outside financial influence from friends and family. From innocent dinner invitations to suggestions on 'must-have' products for the new baby, the dollars were being seduced right out of our pockets. At the same time, it quickly became uncomfortable saying 'We'd love to, but it's not in our budget' in almost every conversation. It made me feel constantly deprived and I would actually end up spending money to make myself feel better. My husband stopped wanting to talk about our finances at all because he felt stressed out.

After thinking long and hard about our spending habits, I decided there were three main ways that outside influences were sabotaging our budget: social invitations, gift giving, and pressure to buy. Once I specifically identified these influences, it became so much easier to combat them.

Instead of declining every dinner invitation, and feeling bad about constantly telling our friends we didn't have the money, we organised a monthly dinner party for the entire group. We rotate hosting duties, and guests just bring a bottle of wine. Instead of eating out once a week with one or two friends, we now have a festive gathering once a month with everyone all at once - but only pay for a home-cooked dinner a couple times a year! It puts us back in control of how much we spend. I've also realised that people essentially just want to spend time with you, so you can feel free to counter suggest a cheaper and more creative option than going out to dinner. Instead of 'it's not in our budget', I now say 'Would you be up for a picnic on the beach instead? The weather is supposed to be beautiful'. If the plans are set in stone, I say 'We already have a commitment for dinner, but can we meet up with you all for a drink afterwards?'

I also noticed that giving gifts was really adding up. It was so simple to start making my own gifts instead. My favourite is to make chocolate covered strawberries and wrap them up in a beautiful gift box.

To stop caving in to pressure to buy, I've had to change the way I go shopping. It used to be a leisure activity to go with friends on the weekends, but I know I am too easy to influence. It's just inevitable that they will say 'You look great in that, you should buy it', or 'I had this with my first baby, you definitely need it'. Now I shop alone, with a list! I've also stopped taking the bait in conversations. If someone is recommending a $700 mountain buggy stroller, I ask if they know of a more economical brand of similar quality.

The most important way I've stopped outside influence from wrecking our budget is to talk openly about things with friends and family. Through this I've learned that most people are in the same situation. A friend confided that she was deeply in credit card debt and didn't know what she was going to do. Now instead of meeting her for a weekly manicure and lunch date that costs at least $60, we have opened up and become a real support system to each other for reaching our financial goals. It's often perceived as taboo to talk about money with people, but I think our friends have been just as relieved as we are!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

I held a very successful and inexpensive party for my daughter and her 12-year-old friends by doing my own version of the 'Amazing Race'! When sending out invitations, each person was allocated a team colour and asked to wear clothing in that colour. On arrival they were given a back pack containing water bottles, maps of the town (we live in a small town and had all activities within a few blocks of home) dry biscuits to snack on, a list and bag for a scavenger hunt to find things on their travels, a dictionary, sunscreen and their first clue.

I had friends in the area lined up with different tasks to be completed (these included windows to be washed, shooting a set amount of goals at a basketball court, sorting books into alphabetical order, separating peas and corn with chopsticks and many other easy to prepare tasks). Each team had a passport to be stamped when each task was completed and the next clue was handed over at each destination. For the final clue, they had to use the dictionary to work out the coded directions to their final destination - our local swimming pool where they spent a couple of hours playing around before heading back to our place for the party food!

This party really didn't take much to organise once I got into it; just a few friends willing to give up a little time for each task and some imagination. I used items from home to make up the challenges, such as books, jigsaws, basketballs and frozen vegies. It was talked about for weeks afterwards and I used photos from the day to make a photo slide show, which I burnt onto discs for everyone who came!

My mother is chronically ill and disabled. She suffers from a rare type of auto-immune disease, called lupus, and is therefore allergic to most chemicals. This made cleaning difficult because she was allergic to most cleaning products, or those she wasn't allergic to were too expensive to buy on my carer's pension. Because Mum's disease is an auto-immune disease, I have to keep our house hospital-grade clean.

So I have come up with a fantastic recipe, and my house is spotless, smells great and is fresh and clean. The solution cleans and polishes everything, including windows. I have never seen glass and stainless steel taps look so clean.

This solution also lasts forever. Household cleaner used to cost me $80 per month, but now I buy detergent every three months, vinegar once a year at $1.50, washing soda every 18 months at $0.98c and eucalyptus oil once every eight months at $3.50 - a saving of $880 a year minus $20 for the few items I do buy. In total I've saved around $2640 over three years.

Household Cleaner

1 litre water
200ml vinegar
40ml detergent
40ml eucalyptus oil
2 dessertspoons of washing soda

Mix all ingredients together, and it's ready to use. Use 60ml of solution in warm water to wash your floors. Fill a spray bottle and use it to clean your table, benches and bathroom.

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

My washing requires a fabric softener as my laundry gets hard and coarse if they're washed and dried without it, but I hate spending up to $4.00 per bottle, so came up with this cheap solution.

It works brilliantly. I now buy a home brand or extremely cheap hair conditioner (no, NOT a shampoo!) This costs $0.80c to $1.90, per 500 mls or one litre.

All you do is squirt a tiny 10 cent size dollop into your fabric softener holder, then fill up the remainder with very hot water.

I now have fluffy towels all the time, and the cheap conditioner option has worked out to be a bottle every six months or so, instead of spending lots of money per week on commercial 'fabric softeners'.
