We no longer spend up to $5.00 on a birthday card. Now we spend $0.15c at the very most!

All we do is take a photo of the family holding up a sign that reads 'Happy Birthday'. I have had a pile of them printed off and we simply write a personalised message on the back of each photo.

This great idea can be used on any occasion, including Christmas. So say cheese and save bread!

Just one plastic container is all you need to organise your freezer and save a small fortune on storing frozen food! I recently read an article which suggested freezing tasty, home cooked meals in small containers so you can whip one out in less time than it takes to get takeaway. Brilliant idea - but going out and getting all the plasticware I needed to do this was going to kill my miserly budget! So instead I bought just one plastic container that was an ideal size and a huge stack of small freezer bags. Now whenever I freeze a meal, I can line my single container with a freezer bag, seal it and once the food has been frozen, I can simply remove the container as though it was a cake tin! I have a ready-made 'freezer mould' and my freezer is still tidy with perfectly rectangular, scrumptious meals in minutes!

This simple tip saves money on toilet cleaners and air fresheners! A cheap and easy way to keep the toilet clean and smelling fresh is to make your own antibacterial spray. I have a spray bottle on the window sill filled with water and a few drops of tea tree oil. After each flush, we spray two or three squirts in the toilet bowl and close the lid. It keeps the room smelling lovely and our toilet sparkling clean without yucky chemicals.

Think twice before you buy an expensive bathroom cleaner to clean your acrylic bath, vanity basin and laundry tub. Try Sunlight soap - it works wonders!

After recently having a dint repaired in my three-year-old acrylic bath (the kids were too rough with their bath toys!), I asked a man who repairs acrylic baths, basins, and so on what the best cleaning product was to use on this surface. I was amazed to hear that good old Sunlight soap was the best. He said most of the marketed products available eventually wear the surface and take off the shine, then people have to pay him hundreds of dollars to get that shine back again!

I decided to try it for myself. I purchased a pack of Sunlight soap (four in a pack) for $2.09 at Coles (with even cheaper generic brands available). One cake of soap lasted me for six months - that's just over $0.50c for six months of cleaning the bath, vanity basin and laundry tub. Best of all, it really works! Also, it leaves a wonderful shine; I was really impressed. I use an old sports sock over my hand and foam up the soap, then I clean away - all that soap scum and grime easily vanishes.

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!

Three weeks ago we ended up without a cent to spend on groceries and the money situation for the following week was only slightly better. We had to eat, of course, so I raided the pantry and freezer and managed to get by on what we had. We were also running out of laundry powder and toilet paper so I rationed out these things to make sure we made it through until we could afford to stock up. It meant using less laundry powder per wash and a few less squares of toilet paper each visit, but we got through the week without having to buy anything, saving around $300.

The following week we had only $30 for food shopping. I still had things I could use up in the pantry and fridge/freezer, and the rationing of the laundry powder and toilet paper meant we wouldn't need to buy more until the next week. So I spent our $30 surplus for that week on milk, fruit and vegetables.

Last week we were back to normal but my two weeks of poverty made me realise just how much money I can save each week by using less of everything and trying to use up what I already have in the fridge and pantry. Over two weeks I had managed to NOT spend about $570 and I had also cleared out a stack of canned beans, canned tuna and sardines, frozen vegetables, frozen meat and frozen loaves of bread that were taking up space in my pantry and freezer.

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'.

Instead of paying for one expensive doona, and the dry cleaning costs that come with it, buy two or three cheap doonas, pin them together at the corners, and put them into the same doona cover.

Because cheap doonas are thinner, you can wash them one at a time in your washing machine, and you can also adjust the warmth. When the weather starts getting warmer, just take one doona out of the cover and put it away in the cupboard.

I am on a very, very low income, so I budget for every bill and expense. I put away bill money every fortnight and that way I have all my bills covered as they arrive, and we seem to just spend the rest. Last year I decided to pay me as a bill, so every pay day I pay me first, just $50. I now have over $1200 in savings. I can't believe how easy it is; just pay yourself before everyone else. The first couple of pays it was an effort not to touch it, but as soon as I saw it mounting up, I got very excited. I tell myself all the time that money is power. While $1200 is not much to some people, to me it's a fortune. Try it - it empowers you.

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!
