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!

I have discovered that reversing my old way of shopping is much easier on my pension! Previously I always used to menu plan first, then go to the shops and walk up and down the aisles getting the things on my list (plus plenty that wasn't)! However once we retired I soon realised this was no longer working. I was spending more than we could afford at the supermarket and greengrocer. I needed to find a better way - and I found one!

These days, I do my menu planning and shopping the other way round. I go to the supermarket once a week and buy whatever is marked down. For example, this week I found Wagyu sausages down from $6.95 to $3 for six. That's enough to make three meals for the two of us! I also bought 4kg of chicken breasts marked down to $5.99 a kilo. I can mince some for lasagne, chop some for curries, cut strips for sate or just poach some for sandwiches. Either way I will get at least at least 20 meals for the $45 I spent!

The same goes for the greengrocer. Instead of planning what I was going to buy in advance I now only buy what he has outside in boxes on special. I pick out the best deals, then come home and menu plan around what I have bought. I am finding this so much better on the wallet and would encourage anyone to give it a go!

I created a storage system in my home office that cost next to nothing!

I stacked four white planks, one on top of the other, supported in between by two house bricks at either end. The bricks are covered in bright red fabric to stop scratches and to blend in with the office décor. Instead of buying cane baskets from Spotlight at $22 each, my 20 filing baskets are black mushroom boxes, free from the supermarket. These boxes are strong and sturdy and the perfect size for A4 papers; they even have handle slots, so the boxes can be pulled out easily. I stuck large labels on the front of each box indicating what is inside, and my invoices, accounts, bank statements and so on are now readily at hand.

My storage system is a great time saver, the red/white/black colour scheme looks great and it cost nothing except for the MDF planks which Bunnings cut to size to fit my space. I saved over $400 on the baskets alone!

Pleased with how well this worked, I did a similar thing in my craft room, to store and organize all my sewing, patchwork fabrics - immediately visible when the box is pulled out – knitting wools, card making paper and supplies. I covered the boxes in pretty pink wallpaper off cuts bought for a few dollars from a garage sale. Same story in the kids' playroom, where their storage shelves acts as a room divider. The kids have painted crazy designs on the boxes, which hold colouring pens and pencils, card, paper, scissors and toys. The kids are allowed to pull out only one box out at a time, so the toys are always cleaned up and put away before the next one can be pulled out.

Simple, cheap as chips and such a stylish way to stay organized!

We have been growing our own vegies, with quite some success, however we had a problem with white butterflies laying their eggs and producing green caterpillars which would attack our precious crop! I had heard that these butterflies were territorial so I came up with a brilliant solution to our problem. I made replica white butterflies,(out of waterproof ice-cream container lids) that were the same size as the real ones I then skewered them onto bamboo sticks and placed them in amongst my vegetables. Result: No more butterflies! It really works- I've watched them whilst having my tea break. As they fly over our garden they see there are already several there in our veggie patch, so they fly on over to the neighbours gardens! It sure is a cheaper and more environmentally-friendly solution than any other pest control I've heard of!

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.

I was usually a pretty prudent shopper but was always looking at the money I saved as potential cash for more purchases. This meant that in the long run I didn't really save anything and ended up with a heap of things I didn't really need.

I started taking a 'savings purse' with me to the supermarket when I did my grocery shopping. Instead of buying the product I would normally have bought, I would choose the cheaper alternative. For example, I would purchase the 'home brand' biscuits for $1.00 less. That $1.00 would go into my head as a saving. At the end of that shopping trip I would put any 'savings' into the savings purse. I was stunned. After two weeks of shopping and 'saving' this way, my savings purse contained $100.

I began to use my savings purse in other ways. If I managed to refuel my car with cheaper fuel, I would put the difference in the purse. If I wanted a chocolate bar, and I resisted buying it, I would put that money in my savings purse. Even with those small amounts, the savings became huge. Doing this began to be fun; it was a challenge to find extra ways to put money into my savings purse!

To top it all off, not only was I saving money but, by 'resisting' the sweets and chips so that I could put the money into my purse, I was also eating healthier and losing weight. I am so happy with the results.

I pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!

I had been living beyond my means for some time and knew I needed to trim my spending. For the last couple of years, I had been pretty careful with purchases, but was not succeeding in 'cutting my coat according to my cloth'. About eight or nine months ago, I decided I would only spend cold hard cash. I withdrew what I could afford to once a week from the bank and forced myself to make do with that until the following week. What a shock! The first couple of weeks, I was penniless within 24 hours and had long lists of unpurchased 'necessities'. My grocery shopping barely covered the bottom of the trolley. (What a joy when it came to unpacking it!) I discovered I could do without many things and started making all food (including bread) from scratch. Most things tasted better and I enjoyed cooking. I started buying vegetable seedlings and growing them, but have had to trim that back to seeds to supply us with enough. The junk food and alcohol are long gone - the money never makes it that far. I lost weight! But I still wasn't making ends meet, so I had to cut back on contents insurance. The result has been that I am more careful with what I do have and am becoming less concerned about material possessions as I am not acquiring expensive new ones anyway. I had more free time on the weekends as I didn't 'have' to scour the newspaper for the best buys and then rush around putting them on the credit card. However I still needed to trim my expenses, so I had to forgo my medical insurance. I find I am now so much more careful with my lifestyle, diet and exercise and I suspect it is because my subconscious knows that there is no comfortable private hospital or top specialist waiting for me if anything goes wrong.

Petrol is still a thorn in my side and I am very conscious of the percentage of my hard-earned money that is going on harming the environment just to get me to work. Tomorrow I have an interview for a less 'glamorous', but otherwise similar job within walking distance of my home. This would also increase my exercise. So far, the follow-on effects of spending only cash I have in my hand have not ended. But each time I have had to make a tough decision about which 'necessity' to forgo to live within my means, I have discovered that going without is not as bad as I feared and that, oddly enough, I am now healthier, happier, less rushed, more in control of my life and proud of my resourcefulness than I ever was when I had everything I thought I needed.

Keep glass showers sparkling clean for months at a time by using baby oil. First, clean the glass on the inside of the shower well, then dry off. Next, take a soft cloth and smear a small amount of baby oil. I stress a SMALL amount to ensure no oil runs down to the base of the shower, creating a potential hazard. Pay extra attention to wiping the edges and bottom of the glass. Once you have done this, the glass will look smeary and quite awful really - until you have the next shower! The hot water heats the oil and smooths it out on the glass. I have never had the problem of any oil running down onto the floor, even after heating it. You'll find a very small amount goes a very long way. Basically, the soap scum cannot attach itself to the glass, which stays clean and clear for at least three months at a time. By needing to re-apply the baby oil only every few months, this adds up to a huge saving in expensive bathroom cleaners!
