Our family is living proof that with a sensible outlook and good, honest hard work anything is possible. Our 'ugly duckling' house has gone from being the worst house to the best house in the street. Unfortunately the cost of renovating and extending it cut into our interior design budget. However we discovered that we could still furnish our dream home beautifully on a reduced budget by settling for second hand items.

For example, our curtains are fully lined and are gorgeous! One window was not a standard size and the quote for its curtains alone was $1500. Instead I found a perfect set at the op shop to fit our huge window for only $40! We have now finished the curtaining for a total cost of $250, saving us $5,000 on the original quotes. We have also bought stunning soft furnishings such as cushions, throws and floor rugs, again from op shops. Furniture we have picked up either second hand, from op shops or passed on from family. We have painted and scrubbed these pieces and now have a very up to date 'beach/country chic' look, all for little cost. The house is now finished and it looks stunning inside and out. We have Edwardian steamer chairs outside on the balcony bought for $2.00 each from the op shop. What a bargain! Our friends and family are amazed.

We now go to op shops first for all of our clothes. Our teenage kids really appreciate their 'brand name' bargains, such as polo shirts for $8 where the normal price would be $100 and many other items. I recently bought my husband a brand new dinner suit on "half price day" for $7.50! When you buy from op shops you pay cash - no credit card debt for us!

Every spare cent goes into paying off our mortgage and the house is almost paid off. We have worked hard doing a lot of building and landscaping work ourselves, as well as the interior, to save money. We live like kings but our outgoings are carefully calculated. We have taught our kids the benefits of hard work, and sensible spending. We are very proud of our lifestyle and the happiness it has brought us.

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.

I feed my family of six on a little over $230 a fortnight with a bit of planning and a lot of baking! I buy a bulk 2kg pack of beef mince from Aldi ($11) and a 2kg pack of chicken ($20) as well as jars or packs of sauces. I separate the mince into four 500g lots and make rissoles with one lot (adding grated carrot and zucchini), then I put the rest away for spaghetti, pasta bake and burrito/taco night. This makes four main meals and we often have leftovers for lunch the next day.
I take three or four of the chicken breasts and slice them in half or into thirds, tenderise them with a mallet and cook them for sandwiches. I slice and dice the rest of the chicken for stir fries, casseroles, wraps and burritos. This gives me another four or five main meals plus leftovers. This way I spend around $230 on my main shop a fortnight, including nappies. I bake a lot which cuts back on the cost of expensive snacks for the children and I always have a pack of jelly on hand to 'treat' them when the cupboards are really bare
I also plan my meals around what fresh veggies I have in the fridge and leave the frozen ones until after I have run out of fresh ones, and I alternate rice and pasta with couscous and potatoes or cauliflower bake.
It just goes to show that frugal and planning don't have to mean boring!

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!

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!

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

Follow Jamie Oliver's example and make your own chicken nuggets - it's healthier and cheaper! We used to buy the cheap brands of chicken nuggets but after realising how much of their content was fat/skin/fillers and other unmentionables, we switched to only buying breast nuggets or pieces. However, this soon proved really expensive and they often still have fillers. So I came up with a better way and found this home-made version is much tastier too!

Buy chicken breast fillets or tenderloins on special - I usually get them for between $9 and $10 a kilo. If using breast fillets, slice them into smaller and thinner pieces. Remove the tenderloin as one piece, then fillet the chicken into similar sized bits. Dip them in melted butter, then roll in breadcrumbs (press on firmly). I often use hot and spicy breadcrumbs, or stuffing mixes to add more flavour to the crumbs, but you can just use leftover stale bread crumbed in the food processor and save even more money! Layer the chicken in baking paper, then cover in plastic and freeze until frozen. Remove and separate into ziplock bags or suitable storage container.

When ready to cook, place in preheated oven and bake at approximately 200°C for half an hour, depending on the size of the pieces. Small boxes of prepared commercial fillet pieces/tenderloins cost approximately $7.00 for as little as 400g. In comparison, a one-kilo batch for $10 makes at least three times that amount - and without any junk fillers, additives and skin!

I am a 39 year old mum with five children. I love to have soft skin, but I'm not keen on all those chemicals in general moisturisers. I like natural skin care creams, but they come with a hefty price tag. Thankfully, my grandmother gave me a perfect, all natural solution.

She suggested I try coconut oil, as she had used it as a skin moisturiser and hair conditioner while she was growing up. I purchased a 400ml jar of organic coconut oil from my local health shop for $10.70. I now use it every evening on my face, and every morning as a body and face moisturiser. I also use it as a lip balm and once a fortnight, I melt 1/4 of a cup and apply to damp hair. I then pop on a shower cap, wrap my hair in a towel and experience a moisturising hair pack that smells divine.

My skin has never looked better and my normally dry, curly hair is now soft and shiny. The jar I purchased six weeks ago is still half full and I estimate I will save $380 a year on moisturisers, hair packs and lip balms. Best of all, it's chemical free.

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!

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.
