Bundle up your bags and don't get caught short

I have come up with a super easy way to solve my shopping bag dilemma! Like many people, I was sick of trying to organise a whole bunch of bags of different shapes and sizes in the back of the car, ready for shopping trips. I really like my car to be free from clutter, so wanted a thrifty and simple solution, I decided to use an old cosmetic purse and filled it with 99c reusable nylon bags from the supermarket. These roll up tiny and fasten with a elastic tab, making a neat and tidy little roll. I can fit eight of the tiny rolls into my cosmetic purse and this in turn fits nicely into my handbag or centre console of the car. These days I never get caught without a bag and these ones can get used over and over again. Being made of material, they can also be thrown into the washing machine if they have had meat or something drippy in them and are soon as good as new again!

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!

$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.

Puzzling our way to a new house

My husband and I have finally found the key to successful saving! The two of us are dreadful savers; while we're good at putting spare change in a jar, we don't know what to do with it once the jar is full! We thought a saving thermometer would be helpful, but wanted something that wouldn't be so obvious when people came over to visit. So we came up with a more subtle brainwave - a jigsaw puzzle!

We bought a jigsaw of what we wanted (a house) and assigned a dollar amount to every piece. Now we 'buy' pieces of the jigsaw puzzle, the money goes in our jar and we bank the money once a month. We even set up challenges for ourselves, such as who 'buys' the most pieces in a month, and we never have to worry about what to buy each other for presents - we buy pieces of the puzzle of course! Once we've completed the puzzle we're going to hang it on the wall - of our new house!
