I am richer than I've ever been thanks to my Simple Savings outlook. When I first joined SS I made a number of small but significant changes to my life and the savings and benefits immediately began to add up. Here are a few of them:

I almost halved my grocery bill in a month - it went from $815 in February to just $430 in March when I started shopping at Aldi and carefully tracked every cent. I discovered my 'inner baker' and instead of buying cakes and biscuits, I baked them from scratch at home. When my washing machine broke down, instead of having to pay out $700 for a new one my wonderful boss gave me an old spare machine they had and no longer used. I made two calls to my insurers, one for my car and one for my house, and found I could save $150 and $400 respectively on my yearly payments. I checked my mobile plan. Because I hardly use it, it was not working in my favour. I changed to a prepaid plan and now what I spend is what I use.

And, finally, I stopped looking for another job to earn extra money. Every dollar I save means time I don't have to work. I am now building my 'wealth' every day in more ways than one.

Many of my friends I used to envy have new cars, impressive houses, expensive clothes - and huge credit card bills. They holiday in Bali or Queensland but work 40 hour weeks in order to do so. They pick up tired and stressed children from after school programs and feed them take away foods because they're too short on time and energy to cook from scratch.

I have a 13-year-old car, a 1980's house, cheap clothes - and NO credit card debt. We holiday three times a year for a week at a time in our trusty 80's caravan and I work 20 hours a week, during school hours, for four days a week. I have one day just for me (or housework). My children walk to and from school and come home to baked goods, home-cooked meals and a happy relaxed household. I'm there to oversee and help with homework and I watch all their sports games.

Ask me again if I want another job to have the 'stuff' I once thought I wanted/needed and my answer will be a clear, precise, 'No way'. Thank you Simple Savings for helping me to step back and see what's really important in life.

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.

Why buy lunch? With recipes as good as this, there's no need! I make this egg slice every few days to take to work, and I thought you might like to try it too.

Ingredients:

2 cups vegetables – just about anything will do. Leftover roast vegetables, steamed vegies, wilted salad... even raw stuff like grated carrot or chopped up tomato.

1/2 cup leftover meat, for example, bacon, fish or chicken

4 eggs, beaten

Grated cheese

Method:

Spread the vegetables and meat over the bottom of a greased square baking dish. Pour over the beaten egg, top with grated cheese and bake at 170C for about 30 minutes.

I take a quarter of this slice and some salad to work every day – it's yummy hot or cold. Thanks to the wide variety of vegetables you can use, no two slices are the same. It costs less than a dollar to make and the vegetables and protein keep me going for hours.

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

Swapping roles with my husband forced him to start budgeting and to learn to take control of our finances!

My husband and I are happily married and are about to celebrate our 50th wedding anniversary, but there was a stage in our lives when we were raising three children and our finances were incredibly stretched, yet he refused to accept it.

One day there was no bacon for his breakfast (he likes bacon every day) and he lost his temper. Rather than get angry back, I wrote him a letter resigning as housekeeper, mother and wife and gave it to his secretary.

He finally agreed to talk and I got him to agree that for one month he would take responsibility for running the house on the budget I had been working on. It wasn't long before he asked 'How on earth do you manage? We need to reassess our finances'.

Since then we have always cooperated when it comes to getting through a tough period.

We decided to get rid of the $96,000 mortgage on our home within three years. The massive load of interest we would pay to the bank was over the top and we felt that the bank owned us. The entire family bought into the project one hundred percent.

1) We replaced the nice modern cars with older, less costly ones. The net difference and any savings we had and $700 from a garage sale were paid off the mortgage.

2) We agreed to budget as if we were in a life and death war and the war had to be won in three years. I developed an Excel budget spreadsheet and we tweaked the numbers until we had a 'do-able' weekly saving of $220 extra to pay off the mortgage. Clothes purchases would be done exclusively at 'Harrods', our Salvation Army shop, until the war was over.

We decided to run any item not budgeted for over three 'hurdles'.

The first hurdle was 'could it shorten the mortgage war?'

The second hurdle was 'is it a health issue?' and if so what was the least-cost workable solution?

The third hurdle was 'could it wait until the end of the three years?'

3) As time progressed we became pretty smart at reassigning money to reward ourselves for enduring the war. This meant we could have a low cost take away sometimes, or spend on an out of budget item we had set our hearts on.

It took nearly four years to knock off the mortgage. Yes, we won the war a little later than hoped, but we won. If it had taken eight or nine years to win, it would still have been worth it.

The legacy of our war against the mortgage is that we have developed great money saving skills for life. And life is great.

Christmas 2009 was the worst I ever had, having just separated from my husband. At almost 50 I found myself homeless with no money. On the 16th of December I found a share accommodation but had to borrow money from friends to pay for my bond and two weeks rent so that I could have a roof over my head. The only job I was able to do to keep me going was as a housekeeper, yet I could hardly pay for the petrol to get to work.

For four weeks, I avoided going to the shops. I am 90% vegetarian so decided to grow all the vegetables I like to eat at my rented home. I collected some seeds, seedlings and cuttings from friends and customers and decided to spend my last $10 for chicken wire to protect my homegrown herbs and vegetables from possums and bush turkeys. I am spending time tending my garden every day and I now have lettuces, beans, cucumbers, cherry tomatoes, herbs and so on for salads and stir fries every day. I even have enough to give some to my friends and customers to thank them for helping me to stand on my own feet and living a healthy life. This week I only spent $16 for organic eggs, milk, a tin of pink salmon and a loaf of bread. These with my homegrown herbs and vegetables will give me a healthy diet for the whole week. I am saving heaps to pay my debts as fast as I can.

At soon-to-be-50 and with no savings, I bought The $21 Challenge book to challenge myself. I am so excited because I spent years of feeding a family of four and now I am alone I have absolute control of what I spend and what I put in my mouth. I feel liberated, I feel young and full of energy. Having less money in 2010 is more enjoyable than my stressful life in 2009!

I have decided I want a house which I can clean in minutes and I don't want any more energy or money draining clutter that makes it harder to control. The more I have the harder it is to control and the more motivation I need to contain it. 'Less is more' is my new mantra! I am applying this principle to my finances as well - when I buy too much it is such a burden and I don't have the motivation to stay on top of all the bills. Therefore, less is more - more energy, more money and more happiness!

Watching my 'non-Simple Savings' sister unpack her groceries this week made me realise how much my shopping habits have changed in the year since I discovered Simple Savings. I used to love supermarket shopping, wandering the aisles for hours, one of this, one of that.

Some products I just don't buy anymore include:

• Liquid handsoap - I now make my own (my first SS project from the Vault). Saves $40/year.

• Spray and cooking oil - I buy 4L of good olive oil on special for about $20 and use a refillable hand pumped spray container (from House, $15 - will last years). I used to buy cans of olive oil spray at about $3.50 each and by changing how I buy oil, I am saving $100 per year.

• Cleaning products - are now missing from my list - we use bi-carb and vinegar and other simple Vault tips.

• Dishwashing cleaner - has gone too. We use citric acid, which I normally keep for my yearly lemon cordial making.

• Soft drinks and cordials - are rarely bought now - we use juice as you would cordial, and have changed our habits in favour of water.

• Yoghurt - we make EasiYo using packets bought in bulk from GoldenGlow online. Saves about $150 a year.

• Eggs and vegies - in the back yard!

• Condensed milk, Yogo, cake and pancake mixes - we M.O.O. ('make our own') using Vault tips.

• Icypoles - M.O.O. using tinned fruit juice or other - search the Vault!

• Magazines - I never buy new, just pick up the free supermarket recipe brochures or occasionally buy some gardening ones from the op shop.

• Junk and pre-prepared foods - we buy a lot less in favour of having our own 'sausage roll make-athons' or other baking with the kids.

As well as noticing the presence of many of the above things in my sister's shopping, I also noticed she buys small quantities of lots of items I now buy in bulk. Each week she has to mentally or physically check if she 'needs another of...', where I buy large amounts from the supermarket and other cheaper sources - and then don't need to think about it again for at least six months. These types of products include:

Washing powder (I'll never buy less than 20kg, and with the Vault advice to reduce our amount per load, this is lasting ages!), teabags, coffee, shampoo, dog and chook food (from pet supplier every six months), ham and meats(buy large piece of ham and store in ham bag per Vault tip - saves at least $50 a year over my previous habit of buying little cute packets of 50g each), bacon (buy from ALDI and freeze), dishwashing powder (ALDI brand is MUCH cheaper than the Finish tablets we were using - saves us $150 a year at least. I buy 12 months supply on one of my ALDI runs), cheese (buy larger amounts less often and freeze if necessary), rice (10kg bag much cheaper), jelly crystals (I bought 5kg bag at IGA last week - makes 20 serves for same cost as three individual packets), tinned fruit, soup, tomatoes and other products (from SPC outlet), nappies, paper towel and toilet paper (I buy lots when on a fabulous special). Fruit and veg I buy from the greengrocer, the market or grow my own. Meat is from the butcher, chicken from the poultry shop and fish from the fishmonger once every three months.

I could go on for every grocery item - nearly everything has changed in 12 months. This is even without noting the savings from changing products - for example, I used to think myself very clever if I bought my Uncle Toby's quick oats on super special for $2.00 per kg box - until I discovered I can buy Home Brand, which I cannot fault, for $1.00 a kilo all the time. Same for most basic products.

With changes like these to my grocery shop and to our home loan, insurance, shopping habits and so on, Simple Savings has saved us thousands of dollars in our first year of membership. Our lifestyle has actually been RICHER since SS. I didn't set out to change my shopping habits - I just started by making handsoap and buying Home Brand porridge oats - but suddenly I have realised how large this change has been. If I see you at the supermarket with your milk, bread, 8 large packets of toilet paper, 6kg of the super special meat, 10kg of rice and three-litre containers of vinegar, I'll know you caught the bug too!
