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.

A novel idea to help my Mum save on new ceiling fans has led to some fantastic and unexpected long-term savings! After being quoted a whopping $160 per unit (pensioner rate) to get ceiling fans installed, we took matters into our own hands and placed an advertisement on local notice boards. It read: 'Experienced licensed electrician required to install three ceiling fans. I would like to trade the costs by doing your washing and ironing for one month.’

Within a few days, Mum had received several enquiries and selected a nice, young single guy who needed a 'mother's touch' to some of his clothes - a lot of stain removal and buttons re-sewn. He installed the fans and dropped and picked the clothes up from her place on a weekly basis. To our surprise we learned he also had connections to plumbers and gardeners and she was soon able to have her bathroom wall retiled in exchange for scrubbing out an oven and re-organising a food pantry for a couple that were having a baby soon.

It didn’t stop there! Before long she was taking up hems, sewing on buttons and doing basic mending in exchange for garden maintenance and mowing lawns. These guys are ripping up old items from homes every day with their trades so these days they even search around to find her the cheapest - or even free - items if she needs them, as well as providing an oven door and dials on her heater for free. They often come across things that others could use but end up in the tip instead.

As a pensioner, Mum has time on her hands and is very experienced in household chores but has a limited income. This trade of skills and services means she can now carry out tasks within her ability and has made some fantastic friends. Her place looks amazing and is she even happy to do babysitting for the families. In turn they really appreciate having a cuddly grandmother figure around. She has a new purpose and a whole new social network too - in fact she looks 10 years younger!

Transforming myself from a shopaholic to a smarter consumer has enriched my whole life. Not only am I saving money, my life has become deeper and more meaningful since I decided to live by the following rules:

• Keep away from the shops.
• Buy only what you need.
• Buy second hand if you can.
• Be stylish, not fashionable.
• Don't buy what you can borrow.
• Stop reading glossy magazines that encourage shopping.
• Borrow books and magazines from the library.
• Read about simple living.
• Do it slowly.
• Spend more time with your family and friends.

These rules may sound simple, but they have changed my life. For as long as I can remember, I have loved shopping. I could easily do it all day, every day and never tired of it. I enjoyed the quest to find bargains or something I had 'always' wanted or didn't yet have.

When I felt angry, sad, lonely, fat, old, poor, disappointed, rejected, embarrassed or simply 'not good enough' - I went shopping. It made me feel better.

When I felt happy, confident, rich, delighted, loved, appreciated and 'on top of the world' - I celebrated by going shopping.

Although I work full time, I had never paid off my credit card and financially I was always struggling. Then I heard about climate change and the impact my shopping was making on the environment. That's when I decided I would stop shopping all the time.

At first, this decision left an enormous vaccuum in my life. I used to be very busy - 'Never enough time in the day' was my mantra. Then suddenly I had lots of free time! I didn't have many really close friends, except my mother and sister. We often used to meet for a coffee and a chat while we were out shopping. But with all the free time I now had, I realised I had been too busy to make other meaningful friendships because of my constant shopping.

I don't meet my mum or sister at the shops any more. We now get together in each others' homes and, although I have always enjoyed their company, I rediscovered a deeper connection with them. We talk, laugh and cry for hours and hours. I am learning so much more about them. I have started to deepen the friendships I have with people who were just 'acquaintances' before. Instead of shopping, I invite them over for a cup of tea or lunch or for a walk along the beach. I'm even starting a book club.

Due to the money I was able to save from not shopping so much and because I wanted to entertain more, I rented out my small unit and moved to a lovely old house. However I soon realised I needed more furniture, so I bought it all very cheaply, secondhand from eBay. Everyone who visits my home says how wonderful and stylish it is. I love making cheap, affordable meals for my friends. I had my first party on New Year's Eve and 35 people came, each bringing their own meat, drinks or salads. To any shopaholics out there like me, it IS possible to change - I'm living proof!

I recently noticed my elderly neighbour was unwell and no longer able to drive or leave the house; relying on taxi services to deliver food (often expensive pre-packaged items), or he would have home delivered takeaways. Being a fussy eater, he was reluctant to consider 'Meals on Wheels', so I volunteered to shop for him and cook him three different meals a week. Each week he gives me enough money to cover the costs of his meals (soups/stews/freezable casseroles) and I make up bulk amounts of each dish. I deliver half to him and keep half for myself, as suggested by him for payment. Not only is he saving money on taxis and home delivery, but he is eating healthy food and my family is also provided with three meals a week as a bonus for giving up a little of my time. Often cooking for one is not inviting, but cooking for others encourages healthier eating habits and helps regain social contact. Often a lonely person will gain a new lease on life to boot. A great savings all round, and using recipes from the Vault saves me even more!

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!

Make all your leftovers taste fantastic with this bulk white sauce mix. Makes enough for 24 servings and you can keep it in the fridge:

2 cups (500g) powdered milk (I use skim)
1 cup (250g) plain flour
2 teaspoons salt
1 cup (250g) butter or margarine.

Combine dry ingredients, add butter and blend until mix resembles dry breadcrumbs. Put in large air tight container. Store in fridge. Use within two months. I label the container with the date and method.

Method:-
To make sauce combine, 1/2 cup mix to 1 cup
cool water. Add flavourings to suit, for example, curry, vegetables, onions, cheese, whatever you like!

My grandson turned six on Boxing Day, and I came up with a new idea for a birthday present that will bring him lots of fun over the next six months. It's called a 'Promise Photo Frame'; here's how it works.
 
I bought a large photo frame with spaces for six different photos. I then downloaded ClipArt pictures of various activities and put them in the spaces with the following captions:
 
Trip to Beach with Grandma
Trip to Zoo with Grandma
Train ride with Grandma
Trip to playground with Grandma
Dinner out with Grandma
Movies with Grandma
 
My Grandson can choose one activity to do with me each month, and when we go out, we'll take a photo of the actual event to put in the space on the frame. This gift, and the activities, can be modified to suit all children, and even adults.

During my uni student years I developed a menu-planning and grocery shopping system that allowed me the freedom to eat well, generously fuel my bicycle-based lifestyle, entertain guests regularly and experiment with new recipes, all within my strict food budget of just $15 a week!

It works like this.

1. Decide how much you will spend on your weekly groceries. In recent years I have had to increase my spending to about $21 a week due to rising food costs and CPI, but the system still works really well when I use it and is a great way to separate needs from wants.

2. Choose the staples and basics that are to be made every week as needed. These could include soy milk, tofu, sourdough bread, yoghurt, sprouts, hummus, fresh lemon cordial, Anzac bickies, gomasio or whatever else you require.

3. Give the ingredients needed to make these staples first priority when making the weekly shopping list. If you have a local food co-op you can buy mostly organic ingredients with minimal packaging in exactly the amounts you need.

4. Check what else is in the fridge, cupboard, garden or neighbours' garden and pore over your large collection of second-hand recipe books to see what can be created with these other ingredients. Recipes which require two or less extra (and inexpensive) ingredients are preferred and a list of these and their corresponding cookbooks/page numbers is made and stuck on the fridge. There will usually be a selection of mains, side dishes, desserts, treats and beverages on the list.

5. Give the extra ingredients needed for the chosen recipes next priority on the shopping list. Over time you will intuitively know when your shopping list is 'full'.

6. Once out shopping, specials of the day such as a big bag of discounted apples or cheap cooking tomatoes take third priority. If not consumed within the week, these can form the basis of recipes chosen for the following week.

7. Last priority (and usually only considered after the register shows you are still under budget) are those inevitable temptations that one wants rather than needs. It often helps me to take my recipe list with me and remind myself that I can make a delicious self-saucing carob pudding at home for a fraction of the cost of the tiny chocolate bar I am now contemplating. All of a sudden the money seems much better spent on a kilo of brown rice!

8. Back at home, simply cross the recipes off the list as they are made. There will always be plenty of food for dinner parties or last-minute guests, and the sometimes tiresome decision of 'what to cook?' becomes easy.

Using this system I have never run out of food or felt like there was 'nothing to eat'. In contrast, I have stayed at many houses where, despite having pantries and fridges which are bursting with food, the occupants have driven to the supermarket and easily spent $30 or $40 just to cook up dinner for the night.

Seems unbelievable? Try scratching every processed food item off your own shopping list and see how many more kilos of real food you can come home with for the same amount of money. Don't forget too, to keep an eye out for trees in public areas which are loaded with fruit or nuts. I have used the $15 a week food budget for stretches of up to a year at a time, which means I certainly wasn't relying on stockpiles of food from more extravagant days tiding me over. Necessity breeds creativity, and I am so happy to have been forced early on to examine and separate my wants from my needs in this regard. Even when times are tough, I know I can eat well!
