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!

I make home-made yoghurt in my EasiYo maker for as little as $0.50c per kilo. You don't need to buy the special sachets, all you need is milk powder and a couple of tablespoons of plain yoghurt. I just use 1 and 1/3 cups of milk powder and two heaped tablespoons of yoghurt (saved from the last batch). Easy, cheap and delicious!

A novel idea to help my Mum save on new ceiling fans has led to some fantastic and unexpected long-term savings! After being quoted a whopping $160 per unit (pensioner rate) to get ceiling fans installed, we took matters into our own hands and placed an advertisement on local notice boards. It read: 'Experienced licensed electrician required to install three ceiling fans. I would like to trade the costs by doing your washing and ironing for one month.’

Within a few days, Mum had received several enquiries and selected a nice, young single guy who needed a 'mother's touch' to some of his clothes - a lot of stain removal and buttons re-sewn. He installed the fans and dropped and picked the clothes up from her place on a weekly basis. To our surprise we learned he also had connections to plumbers and gardeners and she was soon able to have her bathroom wall retiled in exchange for scrubbing out an oven and re-organising a food pantry for a couple that were having a baby soon.

It didn’t stop there! Before long she was taking up hems, sewing on buttons and doing basic mending in exchange for garden maintenance and mowing lawns. These guys are ripping up old items from homes every day with their trades so these days they even search around to find her the cheapest - or even free - items if she needs them, as well as providing an oven door and dials on her heater for free. They often come across things that others could use but end up in the tip instead.

As a pensioner, Mum has time on her hands and is very experienced in household chores but has a limited income. This trade of skills and services means she can now carry out tasks within her ability and has made some fantastic friends. Her place looks amazing and is she even happy to do babysitting for the families. In turn they really appreciate having a cuddly grandmother figure around. She has a new purpose and a whole new social network too - in fact she looks 10 years younger!

We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

Making potato wedges at home is much cheaper than buying them frozen from the supermarket. I use my OXO Good Grips apple divider (bought from a kitchen shop) to cut up a 5kg bag of spuds. I give the spuds a wash before cutting them up into eight wedges and one cylindrical wedge (the kids all fight over these ones). After popping them in boiling water for a couple of minutes I put them onto paper towel to dry, then into freezer bags. These are quick, economical and you can vary the seasonings in different bags, and have them on hand in the freezer for a quick snack or side dish.

Our family home is always a clean and happy one, thanks to our weekly raffle! With four children aged from 12 down to two, there is always so much to get done, so we started our very own 'family raffle' as an incentive to get the chores done.

A list on the fridge displays all the categories for a raffle ticket. Some examples are - clean bedroom floor, do a load of laundry, give a music recital, finish homework by 5pm, clean the windows, play with the baby and so on. Every time a chore is completed, the child fills in a raffle ticket with their name and the task done. Then, every week at the same time, we pull out the prize winner. They receive a prize from the discount store - some kind of age appropriate toy such as a pack of cards, fancy pencils and so on, to a maximum value of $5.00. The remaining tickets are pulled out and all are given five points each. Every child who has reached 20 points during the week also receives $5.00. We get so much housework completed this way! We deposit the money in the children's bank accounts online and they are encouraged to save it, or can spend it on something special. This really helps when they need to buy a birthday gift for their friends and can even pay for their own outings and movie tickets. I read every chore they complete out loud and the pride in their faces is worth every cent!

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.

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!

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!
