Keep the straws from unwanted drink bottles

If you have a drink bottle with an internal straw, when the bottle cracks, leaks or dies, don't throw the straw out! Remove it from the bottle and keep it in your cutlery drawer for whenever you need a straw, or keep a couple in your bag for use when you're out. I keep three in a little cotton bag in my handbag for when we order a drink that would normally come with a disposable straw (milkshakes, iced coffees, spiders, soft drinks). After use, I just give the straw a quick rinse in the restroom sink, or wrap in a serviette, and give a good wash when I get home. A simple way to reduce waste and help the planet!

An apple a day keeps green potatoes away!

I have solved the problem of green potatoes in our household! I was constantly throwing out potatoes as we never seemed to go through a whole bag of potatoes in time before they turned green. We are only a small family but I didn't want to buy smaller bags, as the larger bags were so much cheaper. Fortunately I discovered a way to extend the life of them and it's so easy! All you need to do is to keep them in an aerated spot in a gunny bag or bowl (basically out of plastic) with a whole apple . The gases from the apple stops the potatoes from going green, doubling the shelf life of the potatoes. Needless to say, make sure you also check the apple each time you use the potatoes to make sure it's not going bad!

$21 Challenge helps two families

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.

Eucalyptus oil for cleaning

I used to buy a large can of air freshener ($42 per year) plus a can of Glen 20 each month ($71.52 per year) for my home and bathroom. On top of that I would also buy a large spray bottle of Febreeze quarterly ($54 per year). That is a total of $167.52 just for freshening the house each year.

On top of that, there was the additional cost of $9.00 a week on floor washing cleaners and disinfectant ($468 per year). A grand total of $635.52 per year.

Now I buy two large bottles of eucalyptus oil ($22), plus I have bought two very sturdy two litre capacity spray bottles (at a once-off cost of $18).

One bottle is reserved for carpet, bathroom and fabric deoderising and freshening, which now has us enjoying the additional benefits of no fluorocarbons or chemicals being used in our home, and eucalyptus oil is twice as effective when it comes to fighting bacteria. I use two tablespoons of eucalyptus oil per two litres of boiled, spring or filtered water.

The second spray bottle is used as a floor sprayer. I now don't use a bucket and mop. I just sweep the floors, wet the mop, spray the floor as I go with the eucalyptus and, hey presto, clean, deoderised and disinfected floors in one easy go. I use four tablespoons of eucalyptus oil per two litres of boiled, spring or filtered water.

The total cost saving for an entire year has been $448, which is now being spent on music lessons for our children. The house always smells fresh, the floors are cleaner and we've had fewer colds than ever before.
