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.

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!

I have saved $50 in virtual coins in just a few weeks, since I started using my online money jar! I like the idea of emptying out my purse at the end of every day and placing loose change into a money jar to help me to save. The trouble is, I don't really carry any cash on me any more! Whenever I need to buy something I transfer the exact amount onto my debit card then go out and buy it. This ensures I never have excess cash to spend but it makes it difficult to save loose change. So I came up with this idea. Every time I log on to Internet banking I check all my savings accounts and transfer all the cents into a separate savings account called my 'e-Money Jar'. It's working perfectly and is amazing how quickly those few cents soon mount up!

My husband and I have finally found the key to successful saving! The two of us are dreadful savers; while we're good at putting spare change in a jar, we don't know what to do with it once the jar is full! We thought a saving thermometer would be helpful, but wanted something that wouldn't be so obvious when people came over to visit. So we came up with a more subtle brainwave - a jigsaw puzzle!

We bought a jigsaw of what we wanted (a house) and assigned a dollar amount to every piece. Now we 'buy' pieces of the jigsaw puzzle, the money goes in our jar and we bank the money once a month. We even set up challenges for ourselves, such as who 'buys' the most pieces in a month, and we never have to worry about what to buy each other for presents - we buy pieces of the puzzle of course! Once we've completed the puzzle we're going to hang it on the wall - of our new house!

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.

I have turned my love of a good bargain into something far more valuable! Whenever I am tempted to buy something I could possibly do without, I first calculate how much we would save by paying that money into our mortgage instead. For example, I recently saw a new dress on sale for $49.99 - a bargain, right? However, I paid a quick visit to a mortgage calculator website and discovered that if I didn't buy the dress and put that money onto our mortgage instead, it would take a whole month off the loan term and save us $334.39c in interest. In other words, my 'bargain' dress would really cost me over $300!

Looking at my purchases this way has become a really easy and effective way to curb my spending habit. Now I carry a piece of paper in my wallet with various prices on and I can see how much I would really be spending. It's amazing how much stronger my willpower becomes when I check my piece of paper before buying something and find out what its real cost is!

Here's a great way to save heaps of money on popcorn.
 
I buy a packet of 200 Home Brand paper bags for about $3.00 from Woolworths and a 500g bag of No Frills popcorn kernels for $1.16 from Franklins. I smear some butter in the bottom of a bag and pour in about 100g of kernels. I then seal off the top of the bag by folding it over twice.
 
I set the microwave to cook on High for about three minutes but I always listen closely because the time it takes the kernels to pop depends on how much I have placed in the bag. When the frequency of the 'pops' slows to about three to five per second, I stop the microwave and let the remaining kernels stop popping before removing the bag from the microwave and adding salt.
 
For a healthier version, I simply cut out the butter and salt. I sometimes add chilli flakes or chicken salt, however, there's lots of room to experiment with a variety of flavours. Each bag of popcorn works out to about $0.25c per serve, a huge saving on the ready-made variety at the supermarket.

If you've just boiled up a pot full of spuds and are about to tip the water down the drain, stop right now! That water is full of nutrients and vitamins and can be used again.
 
Next time you have potato water, you may like to try using it for soups, gravies, stews, as a base for making stock, liquid in baking biscuits, breads or pancakes, or a broth drink! You can even leave it to cool and pour over your garden plants.
 
I have achieved fantastic results since I started to use the potato water in my home-made bread, rolls and buns. It's a great way to get additional nutrients from our foods and a big water saver.

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.
