Toilet cleaning, deodorising and water conservation has never been easier.

You can kill three birds with one stone by piercing a few holes through the lid of a bottle of vinegar and putting the bottle in your toilet cistern. The weight of the bottle displaces the water meaning you use less water with each flush. The vinegar will slowly seep out, leaving your loo smelling nice and making cleaning easier. When the bottle is empty, simply refill it with homemade vinegar which is simply half a bottle of cheap white vinegar topped with rainwater. Leave for 24 hours and it will be full strength and ready to use.

Now, if we could only get men to leave the toilet seat down...

Imagine getting 14 meals out of a single cooked chicken! It's my biggest food saving and this is how I do it.

Buy a whole chicken (on special of course)! Get a large pot. Place chicken in it and add chunky chopped carrot, onion, celery and mixed herbs (I grow my own so save more money here)!

Boil until the meat is starting to fall off the bone (I have a wood heater so I cook on that, saving gas in winter) Take the meat and vegetables out, reserving the liquid. Serve some of the meat and all the vegetables with mashed potato and white sauce.

With leftover meat, make up some chicken sandwiches and freeze them for quick lunches. Use the rest in curries or whatever other suitable recipes you have.

Back to the liquid. Add a little more water, chop up whatever soup vegetables you have or add lots of lentils, a dash of paprika and salt and slowly simmer to make a few meals of wonderful thick soup. This way, I feed two of us 14 meals out of the one chicken! Not only is it cheap, it is good for you and has helped the purse strings through many tight times over the years.

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

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!

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 have a family of five children and I like them to eat healthy food that is inexpensive. I often try healthy recipes, and have found one for muesli bars that the kids (and Dad) and their school friends love. It's quick, easy, healthy (you know exactly what's in it) and economical.

Muesli bars

1 1/2 cups toasted muesli

(we use the apricot and almond variety; it doesn't have to be an expensive type)

2 1/2 cups of Rice Bubbles

1/2 cup coconut

1/4 cup crushed nuts

125 g butter (salt-reduced butter is good)

1/2 cup honey

1/2 cup peanut butter

1/2 cup raw sugar

1/2 cup choc chips

(I also add a tablespoon of linseed for extra fibre and omega-3 vitamins; they don't even taste this healthy addition.)

Mix the dry muesli, rice bubbles, coconut and nuts in a bowl. Place butter, honey, peanut butter and sugar into a small pan. Stir over low heat until melted. Allow to come to the boil then reduce the heat to simmer without stirring for five minutes. Pour this into the dry ingredients and stir well. Allow to cool to room temperature (about 20 minutes). Add choc chips and mix again. Line a scone tray with aluminium foil and press the mix into the tray until it is flat (you can use a glass to do this). Refrigerate until firm. Slice and serve. Store in the fridge for up to three weeks (if it lasts that long).

These save a fortune. This mix makes just over a kilo of muesli bars (I use a tray that is approx 28 cm x 36 cm and this will slice up to 30 standard size muesli bars). It costs around $3.50 to make (which can be less if you shop around and use generic or Aldi brands of butter, Rice Bubbles and muesli). Home Brand muesli bars are about $1.69 for six ($0.28c each) compared to around $0.11c each for these home-made ones. Uncle Toby's muesli bars cost between $0.40c and $0.49c per muesli bar.

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

My kids love doing things on Saturdays but even a trip to the movies for our family costs $70. So I invented '$20 Saturday'. We could go anywhere and do anything as long as it didn't cost more than $20 for the whole day. One Saturday each month we would find a spot in the street directory that looked interesting and take a picnic, other times we visited free places such as museums or community festivals and the $20 bought a drink, small snack or ice cream. Not every place was terrific but we gave each place or activity a score to rate whether we would like to do it again. My boys talk fondly of things we did together and places we visited on $20 Saturdays and they learn that you don't have to spend up big to have fun.

I no longer use disposable cloths to wash the dishes and wipe down benches.
 
I recently bought two bulk packets of face cloths, giving me eight cloths. Each cloth is the perfect size and thickness for washing dishes and wiping down benches. I use a cloth for a day or two and then throw it into the wash with the tea towels.
 
I have been reusing the same cloths for over a year – just think of the savings now that I'm not buying disposable kitchen cloths every month!
