As school has gone back, and exercise books need covering, I thought I'd share this money and time saving tip.

I bought a box of 100 plastic sleeves, just like the ones you clip into ring binders. These cost me just $1.50. I then cut off the spine and the bottom of each sleeve, leaving me with a piece of plastic that is the perfect size for covering exercise books. The spine of the book fits and holds neatly in the crease, and the overhang is the perfect width for folding over the edge and sticking down. So simple, and at $1.50 to cover 100 books, so economical too.

I have discovered that regularly checking the balance of my everyday bank account and putting just a few cents away into savings each time adds up to some big savings. How it works is this - I check the balance of my everyday account online and then transfer every amount under a dollar showing on that balance, to my savings account. For example, if my everyday balance showed $300.45, I would transfer that 45c to my savings account.

If I transfer 5c every day, then I save $18.25 per year. But if I have as much as 99c to transfer each time, I save $361.35! The more often I log on, the more I save. It works on the same principle as the Money Tin Challenge - except that I had let this spare change slip down the back of the virtual couch for too many years - not any more!

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!

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

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!

I moved to Perth a couple of years ago with very few possessions, two young children and a dog. I stayed with friends for a couple of weeks and really liked the area they lived in.

I set my rent limit to $150 (cheap for city living - but necessary for the budget) and put my name down on the huge waiting list for government housing. I looked at many places - most out of financial reach. The ones I could afford looked (and smelled) bad. I decided I could 'change' the appearance and the smells - but not the budget.

So, I rented the 'worst house in the best street'. I went through a real estate agent and asked if I could meet with the owner. When he came around (which most don't do regularly with managed properties), he was the first to admit the place needed work (mostly cosmetic).

I suggested to him that I would spruce the place up a bit and in return my rent would not go up while I lived there, plus we agreed that I would be entitled to two weeks rent free over Christmas!

I have painted the entire inside of the house for about $200 (including feature walls, and old laminated cupboards) by buying mis-tinted paints and laybying paint specials. I ripped up the old carpets and polished the floor boards (about $150 in equipment hire and food for my 'helpers') I also got second hand carpet for free from the local paper and replaced the old stuff in the kids bedrooms. I got curtains and blinds from the op-shop and sale tables (about $50 in total)

As for the outside - my place looks better than most of the privately owned homes now! A few boxes of lawn seed (about $3.00 from supermarkets), a bit of hand watering and weed pulling and I have a great front lawn.

I built flower beds with bulk seedlings ($0.45c per punnet from the local nursery - discontinued or 'sick' stock). People in the street are always telling me how great the house looks and they can't believe its the same place!

I work and go to university, as well as look after my children - so all this has been achieved over the last two years. My landlord is happy, we are happy and the money I save weekly in rent (between $50 - $60 per week) allows us to go on holidays once a year and have a few extras!

We have found that changing our brand of dog food from a 'cheap' supermarket brand to a vet-only brand has effectively saved us $5,000.

We used to feed our pets a good quality but cheap brand of food, costing around $20 per week in two kilo bag lots. We decided to experiment and switched to an ultra premium brand that is only available from veterinary hospitals and some pet shops. At $35 for a two kilo bag, it was quite a shock and we thought this was a mistake! However, we stuck it out for a month as planned and came to the following conclusions:

1. They gained condition, coats were shinier, softer and thicker and whiskers grew longer and stronger.
2. They had more energy but lost their tendency to behave like children at a five year old's birthday party!
3. They 'pooped' less and the odour of their urine and faeces was reduced by at least 75%.

The biggest realisation was that they only ate their way through half a bag every week, meaning we were now saving $10 a month just on food alone. Plus, we no longer had to feed supplements and we saved money on litter and both time and money on litter tray cleaning.

In the long term, we have found that their odour has decreased so much that they only need a shampoo bath every six months, not every two weeks as previously.

We have also had less trips to the vet and some chronic conditions have disappeared or become easier to manage without medication. A saving of close to $5,000 per year for us. We love our local vet and so do our pets, so we still visit regularly - but only for a cuppa and a chat!

We have saved $500 a WEEK and I've got my life back again! My husband lost his job in October last year, just weeks after I had gone back to work part time to 'supplement' our household. At the time, we had over a dozen payments going out every week, and I really thought the solution was to work more in order to get more money. However, after 6 months of missing my two small children, and working 70-90 hours per WEEK, we made some wise, life-changing decisions. Firstly, we moved house, which automatically saved us $150 per week in rent. the house is further from town but, unbelievably, we now spend LESS per fortnight on fuel than we used to because instead of just jumping in the car now, we plan our trips. This alone gives us a $75 weekly saving. We finally finished paying off our car (another $100 per week), I took our children out of daycare to be the mum I wanted to be (another $50 per week), I on-sold our gym memberships ($26 per week), and we cleared up four other outstanding debts that had been hanging over our heads (totalling $2000) simply through recognising that I had to make the little money we had work for US, not vice versa, and that NEEDING LESS was more important than caramel lattes, trips to Mcdonalds and new clothes. (Oh, and now we have 3 weekly payments, rent, power and insurance- magic!)

My husband is still job searching, and I work 25 hours a week which is what we comfortably live on. I reduced our WEEKLY expenses by nearly $500, which is almost 50 odd hours per week that I no longer have to work. It is SO empowering, and even though we 'have' less, as a family, what we have gained is immeasurable.

To help me stick to my budget, I use the 'purse system', where I allocate a certain amount of money each payday to pay for different things, for example, petrol or groceries.

I found the envelope system aesthetically unappealing and difficult to operate, so I purchased a number of small pencil cases from Office Works; they're the perfect size to fit dollar notes into and any receipts for that particular 'budget purse'. I have a red case containing money for my groceries, a black case for my petrol and so on. They are also attractive enough that I use them as my wallets for these purposes; unlike envelopes, I am never too embarrassed to pull a case out and carry it into a shop. The cases cost $8.00 each but they motivate me to stick to a budget - a huge long-term saving!

I was renting for nearly three years on a medium salary and really just living day by day. I decided that I wanted to get out of the renting cycle, so thought I would become educated financially. I started reading the 'Rich Dad, Poor Dad' by Robert Kiyosaki series of books and immediately I saw there was no way out unless I changed my psychological views dramatically and acted on them.

I started a savings plan by setting up three bank accounts - one for daily spending (which gave me a small amount of easily accessed money), one for bills (which I used to pay credit cards and so on) and one for long term savings (through ING Direct) which was only to be touched for large goal purchases.

I requested my employer split my pay 30% in the daily and 70% in the bills accounts. Once the 30% ran out, I just sacrificed a bit more and went without the usual luxuries until the next pay. I soon found that I would spread the money out for longer until I hardly ever ran out. At the end of each month (or whenever the deadly credit cards had been paid), whatever balance was left in the bills account was transferred to my savings account.

I am happy to say that after three years, I have managed to save nearly $25,000 for a deposit for my new home, whilst accumulating 5.25% interest!
