Renovations need not cost the earth. We just bought our first home and it had a hideous old kitchen with brown contact, broken stove elements and musty cupboards that had seen better days. We wanted a new kitchen but it was going to cost $4000. It was money we didn't have, so I used my brain instead and renovated our entire kitchen for under $100.

I bought:
Two bottles of oven cleaner at $3.99.
One second hand element from the dump for FREE!
Two tins of paint from Kmart for $17.99 and $36.99
Curtains that were faulty and discounted to $20 for two pairs.

I stripped off all the contact, cleaned the cupboards and painted the inside with flat acrylic paint. They are now white and clean inside. Then I cleaned the oven and fitted the element from the dump. It looks great. Now the oven will do us until we get that mortgage out of the way! I then removed the cupboard doors and gave them a coat of enamel paint. I took the door handles off, cleaned them with oven cleaner and refitted them - they came up like brand new! Finally I hung my bargain curtains and my new fresh, white kitchen looks lovely.

My husband was very impressed. All it took me was two days work and $82.96 of supplies. Best of all,I saved $3900 on a new kitchen.

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!

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.

Sometimes I feel as though I've lived on a budget all my life! I live alone in a second floor rented apartment - no yard or garden, just a concrete car park. To combat that 'locked in' feeling, I have endeavoured to bring the outside in for little cost.

I have several indoor plants; beautiful, green and healthy. My small cold water fish tank has two goldfish in it, they are healthy and lively and provide colour and movement darting around. Very cheap pets too, a can of fish food lasts for ages and you can get all kinds of tanks to suit any budget.

I conserve water by using the 'old' water from the fish tank when I change it to water my plants, giving them lots of nutrients! I also use the water left from steaming vegetables to water the plants too.

I have no car, so must walk to get my groceries and other needs. I tell myself this is all POSITIVE. Everytime I walk to the shops and back it is exercise and energy sustainable. I'm not creating any air pollution either!

Almost all my clothing comes from the local opportunity shops - guess you could call me Second Hand Rose! I have three good op shops in my area, which are also great for cheap books, kids' toys - just about anything you can think of!

Frugality is not about being 'mean'; it's often very necessary for those on a fixed and limited income - and it can be a lot of fun!

I've found a really cheap and nutritious way of feeding my toddler when we are out shopping. Most of the shopping centres around us have a food hall and most of them have a roast carvery type place (that sells roast meat, chips, vegetables and so on).

At the carvery, I ask for a bowl of peas, beans and carrots for my baby. Some places have given it to me for free, commenting how nice it is to see children eating vegetables. Other places will charge $0.50c and the most I have ever paid is $1.00 for a 'big' baby sized bowl full. Don't forget to ask if you are buying a roast meal there yourself, because they may throw in a baby sized bowl free.

It's great when I run out of food at the shops, if he eats everything I have taken with us, or if I've taken longer shopping than planned - it's really healthy and cheaper than buying baby food in jars (which my toddler refuses to eat anyway). We have been doing this since he was eating finger foods from around 12 months old. When he was small he used to eat one pea at a time, which provided hours of entertainment too!

There are other vegetables available but we avoid any that have been fried or cooked in oils (like roast potato) and those that have sauces (like cauliflower cheese).

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!

Making potato wedges at home is much cheaper than buying them frozen from the supermarket. I use my OXO Good Grips apple divider (bought from a kitchen shop) to cut up a 5kg bag of spuds. I give the spuds a wash before cutting them up into eight wedges and one cylindrical wedge (the kids all fight over these ones). After popping them in boiling water for a couple of minutes I put them onto paper towel to dry, then into freezer bags. These are quick, economical and you can vary the seasonings in different bags, and have them on hand in the freezer for a quick snack or side dish.

I am no longer wasting leftover avocado, thanks to this simple storage tip! I have always loved avocado but could never use a whole one in one go. I would use about a quarter for my lunch but by the time I went to use the rest it would have gone brown and didn't look very appetising! Avocados can be quite pricy so the expense of wasting so much was very annoying. Then my new partner, who is chef told me how to stop the browning! I didn't realise but the longevity of avocado is due to light. He advised me to wrap the avocado in aluminium foil and then wrap it in cling wrap and put it in the fridge. To my surprise it really works! Now I get to enjoy ALL my avocado and save heaps too!

I can hardly believe it but we have an extra $2000 sitting in our savings account! I have been a stay at home mum for 18 months. My husband earns a slightly above average salary, which allows me to stay at home with our son. We have a modest home, with modest furnishings and modest tastes. We haven't really had a financial plan since we got married two and a half years ago and have just been cruising along, saving a bit some months and spending it other months.

When I first left work I had full intentions of making a budget, planning our meals, organising our lives and generally being on the ball with our finances. Each month when pay day rolled around, I would say 'this is the month where I get organised!' But it never happened. I am the first to admit that I have been lazy, unmotivated, complacent and ostrich-like. I have been a member of Simple Savings for over a year and always thought we were doing OK and didn't really need to know all these ways to save money. I had heard of the $21 Challenge but wasn't really motivated to try it and we were ticking along as usual - until last month.

With baby number two arriving in three months we needed extra storage space so we extended our garage to make room for all our stuff. This extension made a dent in the savings account which although we knew it would, was quite depressing to see the balance dropping and dropping and not going back up. Lo and behold, motivation began creeping in!

I downloaded all our bank transactions for the month and was horrified to find that I had spent an average of nearly $260 per week on groceries for two adults and one toddler. There were lots of other things I was also horrified to see but I started with the groceries as it seemed easiest. Motivation knocked harder. I decided to take charge!

I read the first two chapters of the $21 Challenge on the website, put a copy of the book on my library request list and did a stocktake of my pantry, fridge and freezer. Imagine my shock when I discovered I had enough ingredients to plan meals for the next 19 days! That's not counting meals like scrambled eggs, pumpkin soup and the emergency baked beans on toast. We had enough food in the house to live on for over three weeks! We just needed fresh fruit and veges and that was about it. I didn't quite make $21 but my first grocery shop after doing the stocktake came to $61, down from $258 per week the previous month.

From then on I watched the bank account like a hawk and knew where every cent went. In previous months when the bank account got low, I would simply pull out the credit card and pay it off on pay day but not this month! This month it stayed in my wallet.

It's pay day again tomorrow and guess what? I have spent an average of $160 per week on groceries, saving us nearly $100 per week. By being aware and thinking to myself 'do I really need that?' and deciding 'no', the savings account has increased by a whopping $2250! That figure makes me weak at the knees! I can’t honestly say where the money has been going before now. We don’t have the latest gadgets, appliances or clothing. I am truly at a loss BUT I have to say I'm pretty proud of myself right now! At the same time, I feel a bit sick that I didn't do this 18 months ago, or even 12 or 6 months ago, but I've done it now. I am motivated to change my ways. I have goals. I have the energy to do this and I have Simple Savings to thank for giving me the tools to continue saving. THANK YOU!

Want to freeze cream without it becoming a watery mess once it's defrosted? The secret is to whip it before you freeze it. Defrost it naturally and you would never have known it was frozen.

This method lets me buy brand name cream when it’s on sale, usually as it's reaching its use by date. I whip it up, portion it off into 100ml containers and throw it in the freezer. I no longer have to worry about buying a full container of cream, then trying to think of how to use it all up before it reaches its expiry date. No more waste!
