I have two daughters who live at home with me who are both university students. They both work part-time and pay me $50 a week each for everything. (And I mean absolutely everything!) I had begun to get sick and tired of their wasteful habits! I would find half eaten muesli bars lying around, week-old uneaten fruit, discarded shampoo bottles and toothpaste tubes with enough in the base for three or four more uses, soap in the bin which still had plenty of use left in it and the list goes on! Quite frankly, I'd had enough! I told them to keep their $50 a week and instead they could buy everything for themselves (snacks, lunches, toiletries and so on). I would provide their one evening meal and that was it. I even made them buy their own toilet paper. Well after two weeks they have decided to mend their ways! They just did not realise the costs involved in running a household and admitted they had taken things for granted. I only wish I had done it much sooner, for their benefit and also mine! One daughter can only afford to give me $50 still and her older sister has increased her amount to $70. However, I think things around here are going to be very different from now on as my Sad Sallys strive to become more like Happy Hanna!

We have saved hundreds of dollars on making our daughters' room cosier! We are living in a rental property which we really like. However, our daughters are in the front bedroom and although it has a window, the room itself it doesn't get a lot of sunshine. This makes the room rather gloomy and feels damp in winter. We have a small heater which we use to try and take the chill off the bedroom before they go to bed but using it makes us feel we're watching money disappear before our eyes!

The perfect alternative would be spend hundreds of dollars on installing a skylight but since we're only renting, this really isn't an option.

A couple of weeks ago, I bought a couple of mirrors for $4 each to stick on the inside of a wardrobe. While I was preparing the area, I put the mirrors on the windowsill and to my astonishment, noticed how much brighter the room was when the sun hit the mirrors and bounced off the ceiling. It was as though I'd switched on a light!

By using those two mirrors and angling them slightly, I was able to bring sunshine and some warmth into the room. I have since purchased two more mirrors to make sure I take full advantage of the entire time that the sun hits the windowsill. The room is heaps brighter and feels more cheerful and warmer. It only cost $16 and it was all done with mirrors!

A great way of enjoying a fun activity while learning a valuable skill is to teach your kids to cook. I set up cooking lessons once a week after school for my two girls and their two cousins in our kitchen at home. The focus is on one recipe each week, something they can bake and take home. It's all about the kids having hands-on fun and there is a lot of chatter and laughter. The kids love it!

A few simple lifestyle changes have helped me lose 26.5kg AND slash my food bill by $35 a week! Over the past six months I have developed my own healthy eating and exercise regime. I began by pushing my one-year-old for an hour a day to the park and around the shops at a brisk pace, using our $20 eBay running pram. I also invested in some second hand hand weights and after extensive research on the Internet, I started my own regime of weight training exercises.

Food-wise, I began buying in bulk and made my own nutritious meals, rather than relying on 'ready to eat' microwave health meals. This way I knew exactly what was in each meal and there was never any waste. I started making my own meal plans and eating smaller portions, going from a 3000 calorie-a-day diet to 1500-1600 calories per day.

Under my new regime I soon began to lose the weight, but the real bonus for me has been in the savings I have made. Changing the way I ate and my portion size has resulted in me saving $35 a week over the past 26 weeks! A win-win situation all round. No personal trainers, fancy diet shakes, pills or supplements - I simply used what I had. I feel fantastic and have the energy levels of a teenager! If I can do it, anyone can!

This hint was a saviour during our last $21 Challenge.

The girls were looking for lunch and complained there was nothing to eat, so I found a large plastic platter and put the following treats on it:

A leftover BBQ sausage, thinly sliced

Two slices of leftover bread, buttered and cut into quarters

A diced kiwifruit

Four strawberries

A small piece of cheese, diced

1/4 tin corn kernels in a lettuce leaf

A muffin, cut in quarters

Four leftover chicken nuggets, cut in halves

A dob of cream cheese with a little corn relish mixed in

Four cucumber slices

Four cherry tomatoes

One Vita Wheat, halved

I gave the girls and myself a saucer each, plus a cocktail fork and everything was eaten and enjoyed. Now we often have 'platter parties' for meals and snacks. A novel way to serve up a meal when you have 'nothing' to eat!

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.

Keep glass showers sparkling clean for months at a time by using baby oil. First, clean the glass on the inside of the shower well, then dry off. Next, take a soft cloth and smear a small amount of baby oil. I stress a SMALL amount to ensure no oil runs down to the base of the shower, creating a potential hazard. Pay extra attention to wiping the edges and bottom of the glass. Once you have done this, the glass will look smeary and quite awful really - until you have the next shower! The hot water heats the oil and smooths it out on the glass. I have never had the problem of any oil running down onto the floor, even after heating it. You'll find a very small amount goes a very long way. Basically, the soap scum cannot attach itself to the glass, which stays clean and clear for at least three months at a time. By needing to re-apply the baby oil only every few months, this adds up to a huge saving in expensive bathroom cleaners!

Save on trips to the shops during a chocolate craving, with the most dangerous chocolate cake recipe in the world! It’s called Five Minute Chocolate Mug Cake.

Ingredients:
4 tbsp flour
4 tbsp sugar
2 tbsp cocoa
1 egg
3 tbsp milk
3 tbsp oil
3 tbsp chocolate chips (optional)
Small splash of vanilla extract

Method:
Add dry ingredients to a large coffee mug, and mix well. Add the egg and mix thoroughly. Pour in the milk and oil and mix well. Add the chocolate chips, if using them, and vanilla extract and mix again. Put your mug in the microwave and cook for three minutes at 1000 watts. The cake will rise over the top of the mug, but don't be alarmed! Allow to cool a little, and tip onto a plate if desired. This can serve two if you want to feel slightly more virtuous.

And why is this the most dangerous chocolate cake recipe in the world? Because we are now only five minutes away from chocolate cake at any time of the day or night!

My mother, sister and I have changed our spendthrift ways to help each other out and enjoy quality time and a regular meal together.

We used to spend our weekends shopping. Of course we bought things we did not need. Even worse, we spent tons of money on eating out in the mall! So, we changed our habits! Once a month we spend a day at one of our houses, taking it in turns. The hostess is responsible for lunch and the others help her with a project around her house.

For example, we have painted a playroom, done general cleaning, cleaned a garage, collected items for charity and more!

I save over $300 every time I clean my rugs with this ingenious tip! About 12 months ago I bought three large rugs at a garage sale. They were marked, but mainly from day to day use. I figured even if I had to pay for them to be cleaned, it would still work out much cheaper than buying them new. Was I in for a shock when I rung around to get prices! To get just ONE of my average room sized carpets cleaned it was going to cost me around $100. Apparently they are harder to clean than a regular carpet, hence the hefty price. I was very disappointed and felt like I had just wasted the $110 I had spent on my 'bargain' rugs. I thought surely there had to be a better way - and there was! I rolled up one of the rugs and went down to the local do-it-yourself car wash. I hosed the dirt off the ground and then laid the rug down. Using the pressure spray on the soap cycle, I sprayed the rug, then used the rinse cycle to clean it all off! It was so easy; the high pressure made very light work of all the marks and left no soap behind. Best of all, it cost me less then $10 - a saving of $270 for all three rugs! The rugs dried in a day in the sun and they came up like new. My friends have all started doing this too and one of them swears that her rugs come up better then they did when she was paying to have them done professionally. It gets rid of all smells and marks right down to the backing. I wash my rugs every couple of months as I have three dogs and two young kids and this has saved me a whopping $1620 to date!
