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!

My husband and I have set a goal to pay off our mortgage within five years. We have a way to go, but keeping this goal in mind has helped us to curb our spending.

I worked out that any amount I put on our mortgage is actually worth five times that amount due to the saving in interest. So when I am thinking about spending $20 on a top, I multiply this amount by five and realise that I do not want to spend $100 on a $20 top! That $20 would be much better invested if it was put into our mortgage.

Smaller portions means larger savings, as you'll see in this hint.

After having a little money left over from a gift voucher, I purchased a set of three small loaf tins. (each tin holds 1/3 of a normal cake mix). I made up a chocolate cake mix and baked it in three tins. I kept one cake aside and put two in the freezer as soon as they were cold. This meant the cake lasted three days instead of just one. I remove the bar cake from the freezer each morning and not long after the kids are enjoying their smaller slices of cake, with no complaints.

I have since carried this over to savoury dishes. When I make meatloaf, I put the mixture into one large tin as well as the three smaller tins. We eat the larger meatloaf for dinner and I freeze the other ones for lunches. This is working really well for me and the savings are huge.

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

As part of my $21 Challenge to use all the food in the pantry, I have set up a 'use up soon' basket containing items getting close to their use-by date. This way, I will remember to use things before I have to throw them out.

I love making scones, and my Mum passed on this wee hint which makes my scones even better.

When the scone recipe calls for milk, use half milk and half water. For some reason, the water makes the scones extra light with the added bonus that it drastically cuts down on your milk usage.

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.

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 pay myself to exercise! Now, you may wonder how that actually saves me money. Because my exercise is free, usually walking with a friend or working out to DVDs I've received as gifts, I don’t have to buy expensive exercise clothes or pay for a gym membership. And paying myself to exercise? That gives me motivation. I started with $1.00 for every day I exercised, and increased it to $2.00 a day - still cheaper per week than a single exercise class or gym membership! I wait until I have enough money for a facial or massage, and treat myself.

I find that the end goal of some pampering really works as an incentive to keep exercising. Prior to this, I never let myself splurge on those sort of things. I am now happier, healthier and far more relaxed!
