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.

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!

I am saving around $100 a month on my grocery bills, thanks to a few simple changes to our family meals. I wanted to reduce our food bill and after some thought came up with the idea of making two nights per week a '$2 Dinner Night'. For example, one night we will have something like toasted baked bean sandwiches or stuffed baked potatoes; the other I use up all the leftover vegetables in the fridge to make a self-crusting quiche. This reduces the amount of food we waste and the kids love it. Even the simplest meals can be delicious and filling and the savings we are making from our twice-weekly $2 dinners are well worth it!

Last Christmas, instead of buying everyone gifts, I bought some small gift boxes for $2.00 each at cheap stores and baked mini puddings and mini rum balls (I made heaps from one recipe), which I put in the boxes. I then tied them with a length of curling ribbon to make them look attractive. Everyone loved the goodies inside, and the maximum cost was $20 for at least six boxes.

I will definitely be doing this again this year. It will probably become a tradition - and why not?

We all know how convenient it is to grab a packet of cake mix off the supermarket shelf, but you can save a lot of money by making your own. This recipe is really easy to make and you can store it in the fridge for up to three months or for longer in the freezer.

Ingredients:

250g self raising flour
185g caster sugar
2tbsp milk powder, skimmed or full cream
125g butter

Method:

Sift or process all dry ingredients until combined, and then rub in or process the butter.

To make the cake add:

2 eggs
1tsp vanilla essence
1/2 cup water

When these ingredients have been added to the cake mix, beat the whole lot until combined. Bake at 150C - 180C for 30 minutes if making one cake, or 20 minutes for smaller cakes. For variety, add coffee, cocoa or anything else you like. This is as good as shop bought cake mixes and half the price!

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.

I am a busy mum of two and my home manual helps my husband and I run our home efficiently, saving money and buying us both precious time to do things for ourselves.
The first section outlines the weekly and daily routines. The daily routine buys me 30 minutes to myself to exercise which makes me feel better throughout the day. My husband can also see when things get done, so he knows what to do if he is letting me have a sleep.
I let the girls watch TV until 9am so that I can complete a chore (clean the bathroom, dusting etc) each day. This helps me keep the house clean and tidy, and then I have the rest of the day to play with my children.
The next section covers dinners for the month. I have a weekly list of which dinners we will have and where to find the recipes for them. This saves time deciding what to have plus hubby or anyone who comes to stay can cook too.
The next section is shopping and supplies. I write all the ingredients needed for the month so I know exactly what I need. I keep catalogues in this section so when it’s shopping time I know where to get the specials.
I also asked for a floor layout plan of my supermarket so I don't need to walk down the aisles I don't need anything from. This saves time (especially when shopping with two young children) and money as I am not tempted by things in those aisles.
I also have a maintenance section with dates when items need maintenance done on them, eg. an oil change for the car. This means everything can be budgeted for and planned and it also helps prevent unexpected expenses, like changing gas bottles.
There is also a budget section of the manual which contains the monthly, weekly and annual budgets in it. We write down everything we spend in this section, so we can see where the extra dollars are spent!
Finally, I have an important numbers section such as insurance companies, medical centre etc so that everyone (including people who are staying) can get to them easily.
The manual doesn't always bring dollar savings, but its our way of making sure we don't waste time doing everyday household things so we maximise our family and down time.

I have been receiving your fabulous emails for ages and I thought I'd share a favourite saving hint of my own.
 
My naturopath gave me a tip which saves money and is better for our health too. She said that most hand sanitisers contain chemicals and antibacterial properties that not only kill bad bacteria but also kill off essential good bacteria. The good bacteria on our hands helps to fight off infections and acts as a barrier, so hand sanitisers can compromise our ability to protect ourselves.
 
My naturopath gave me a natural alternative. She told me to buy some small atomisers and a bottle of water-soluble tea tree oil from the chemist. I would then pour about 20 drops of oil into each atomiser, and fill with water – that's all it takes to make your very own antiseptic.
 
These natural sanitisers are cheap, effective and have a lovely scent. An atomiser easily fits into a handbag, and is very handy if the kids get scratches and scrapes after playing – a quick spray on the affected area is all it takes.
 
Tea tree oil really is the best antiseptic around and there are so many uses for it. Happy natural sanitising!

I’ve saved countless dollars on expensive gourmet ice cream by getting creative with the cheaper varieties. My kids love it when I buy them what they call 'special' ice creams. These are the expensive varieties that come in exotic flavours and cost between $7.00 and $9.00 for a two-litre tub! Needless to say, they really are a rare treat. However, during the school holidays, my kids and I became gourmet ice cream chefs! Using a four-litre tub of Home Brand vanilla ice cream (that cost $4.59), we scooped it out of the tub and let it sit at room temperature for a few minutes. Then we mixed green food colouring, a couple of drops of peppermint essence and some chocolate chips into the softened ice cream to create our very own Mint Choc Chip flavour! We placed it in an airtight container and popped it back in the freezer to enjoy later. The kids were so excited to have made their own special ice cream that we have since concocted many different ‘gourmet’ flavours just by adding ingredients from the pantry.

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.
