I have saved myself the frustration of constantly losing items from my sheet sets (and the expense of having to buy replacements) by keeping them all together in a simple but ingenious way! I used to be constantly searching for a full set of sheets and pillowcases in my linen cupboard no matter how many times I tidied it up. It's crazy but, in my frustration, I actually found myself buying new sets! Knowing this wasn't a real solution I finally pulled everything out, put all the sets together and placed all the sheets and extra pillowcases inside one matching pillowcase. Since then I haven't lost a single item! I can easily see my sheets and duvet sets and the kids can now find their sets and make their beds on their own.

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!

For a great-tasting, quick, healthy and inexpensive breakfast, make your own egg McMuffins.

Fry six eggs, using egg rings, (if you don't have any, check your local discount store), fry bacon if you wish, and toast your muffins. Once all ingredients are cooked, assemble egg McMuffins, including sliced cheese and bacon if you like.

Once assembled, wrap each muffin in alfoil and freeze. In the morning, simply take the muffin from the freezer and cook in a moderate oven for 20 minutes. For an even quicker breakfast, unwrap from alfoil and wrap in paper-towel. Place in microwave for at least one minute, depending on microwave.

My kids love these for breakfast, and they only cost around $0.60c each!

I buy Home Brand English Muffins which are around $1.60.

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.

Changing circumstances and a growing familly all added up to us paying a whole lot less off our mortgage than we would have liked. Pretty soon we would have started to go backwards. It was crunch time!

Using the Simple Savings calendar I identified our most expensive habits, and was astounded to see the amount of money that could have been saved. Our grocery bill was always around $200 or more per week. This amount did not include meat or bread that we get from the butchers and bakery.The trouble was, my husband loved all the expensive name brands for items such as chocolate biscuits, lollies and savoury snacks and was convinced that the cheaper or no name products would be tastless and boring. Week after week I would just automatically reach for these items, without even glancing at the alternatives. I knew as soon as my husband saw the packaging, the goods would remain in the pantry unopened, and he would then go and buy the brand name items anyway.

One week I kept mentioning to him that I was going to do a big clean up of the pantry and I was finally going to utilise all those assorted Tuppaware containers that I had never used. That week I substituted his expensive brand of snack foods with cheaper versions, emptied them into the assorted airtight containers and threw the plain packaging out before he could see them!

I also applied this technique to several other items; I would fill cheaper dishwashing liquid into Morning Fresh bottles, no-name hand wash into saved Palmolive dispensers, you get the picture. Our grocery bill went down from $200 to $140 per week - a saving of $240 a month!

When I finally fessed up to what I had been doing, my husband admitted that most of the snacks were just as good as the name brands, you just have to try a few out. All it took was some creative (OK, and somewhat deceitful) way to present the changes, but we have never looked back. Why would we, with a saving of $3120 a year? Plus of course, one very neat pantry!

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!

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.

I saved the price of an expensive handbag organiser by using three $2 pencil cases instead. I have two handbags that I swap depending on whether I am working or with the kids, and always found it a pain to transfer essential items like my wallet and make-up and to quickly find what I need in a big bag. Now my colour coded pencil cases make it easy! The green one holds my full make-up, for the days I have to dash off and do make-up on the train. This stays at home when I'm not in a hurry. The black one holds pens, business cards, USB sticks and so on, and the blue one holds lip gloss, band-aids, paracetamol and post it notes. My items are now easy to swap between bags and I don't have to dig around for smaller items. All for $6.00 and a hunt through the bargain bin at Officeworks!

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!

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.
