I came up with a great low cost, low stress way to feed the crowds at my son's 21st birthday party. With the weather being chillier, the food needed to be warming and more robust than usual. I came up with the idea of a crockpot party! I am borrowing family members' and friends' crockpots and am filling them in the morning with different dishes, then I can 'forget' about them until the evening! When it's time for everyone to eat, I can then just plug them all into a power board and put them on the table. This is a triple whammy saver for me! It saves time as I don't have to spend all day in the kitchen and can get other things ready for the party instead. It saves money as I can use cheaper cuts of meat to achieve tender dishes and - as I don't have to use serving dishes, it even saves on washing up!

Instead of adding up when you do your shopping, why not deduct? This hint explains all.

I no longer use a calculator when I do my grocery shopping. Something to do with always pressing the wrong button and clearing my calculations!

Now, I simply write how much I can spend on my shopping list and when I put something in my shopping cart, I subtract a rounded amount from the total. For example, if I have $100 to spend and I buy milk for $3.89, I subtract $4.00, leaving me a total of $96 to spend on the rest of my groceries.

By making these deductions with every item, you always know how much you have left to spend. Makes it easier to budget and certainly beats using a calculator!

I make these Cheesy Ham and Corn muffins, which are delicious and at only $0.44 each to make, give me and my family something tasty, cheap and healthy in our lunchboxes. They are yummy cold, or heated up in the microwave.

Makes 12

Ingredients:
1 x 310g can of corn (reserve can for measuring)
½ cup reduced fat milk (1/2 ‘can’)
2 eggs
2 cups of self raising flour - I use wholemeal (2 ‘cans’)
Pinch of salt
2 cups reduced fat grated Australian cheese (2 ‘cans’)
2 slices ham, cut into strips
2 teaspoons English mustard

Method:

Whisk together corn, milk and eggs in a large bowl until combined. Add remaining ingredients and stir until just combined.
Spoon mixture into non-stick ½ cup muffin tray.
Bake at 200c for 15-20 minutes or until golden brown and cooked through.

I add a supermarket gift card to my weekly grocery list and use them all up to shop for Christmas! After doing some calculations I realised that the ready-made Christmas hampers that you pay for weekly cost three times their actual value, not to mention the fact that they can include many products you won't ever use. My new system for buying Christmas groceries lets me buy my own hamper full of items at the current price or on special.

Just one plastic container is all you need to organise your freezer and save a small fortune on storing frozen food! I recently read an article which suggested freezing tasty, home cooked meals in small containers so you can whip one out in less time than it takes to get takeaway. Brilliant idea - but going out and getting all the plasticware I needed to do this was going to kill my miserly budget! So instead I bought just one plastic container that was an ideal size and a huge stack of small freezer bags. Now whenever I freeze a meal, I can line my single container with a freezer bag, seal it and once the food has been frozen, I can simply remove the container as though it was a cake tin! I have a ready-made 'freezer mould' and my freezer is still tidy with perfectly rectangular, scrumptious meals in minutes!

Making our own cleaners has saved us a fortune over the years and we have saved the environment a little too. '1001 Greener Household Hints' by John Schluter is full of simple household cleaning ideas and we went straight out and bought some five litre bottles, spray bottles and some of the suggested basic cleaning ingredients. The following instructions are from the book:

Air freshener: Mix one teaspoon of bicarbonate of soda with one tablespoon of white vinegar. Add two cups of water. Store the mixture in a pump spray bottle. Add scented oils for fragrance.

Spray and wipe cleaner: Mix two tablespoons of cloudy ammonia, a half cup of white vinegar, two tablespoons of washing-up detergent and four litres of warm water. We stored this in large labelled bottles and used in spray bottles as needed.

Bathroom disinfectant liquid: Dissolve 12 drops of eucalyptus oil in 1ml of methylated spirits and then add eight cups of warm water. We used this in spray bottles also.

We paid $5.00 for the book but have saved hundreds in the years since we began making our own cleaning products.

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.

My kids love doing things on Saturdays but even a trip to the movies for our family costs $70. So I invented '$20 Saturday'. We could go anywhere and do anything as long as it didn't cost more than $20 for the whole day. One Saturday each month we would find a spot in the street directory that looked interesting and take a picnic, other times we visited free places such as museums or community festivals and the $20 bought a drink, small snack or ice cream. Not every place was terrific but we gave each place or activity a score to rate whether we would like to do it again. My boys talk fondly of things we did together and places we visited on $20 Saturdays and they learn that you don't have to spend up big to have fun.

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!
