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 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.

A novel idea to help my Mum save on new ceiling fans has led to some fantastic and unexpected long-term savings! After being quoted a whopping $160 per unit (pensioner rate) to get ceiling fans installed, we took matters into our own hands and placed an advertisement on local notice boards. It read: 'Experienced licensed electrician required to install three ceiling fans. I would like to trade the costs by doing your washing and ironing for one month.’

Within a few days, Mum had received several enquiries and selected a nice, young single guy who needed a 'mother's touch' to some of his clothes - a lot of stain removal and buttons re-sewn. He installed the fans and dropped and picked the clothes up from her place on a weekly basis. To our surprise we learned he also had connections to plumbers and gardeners and she was soon able to have her bathroom wall retiled in exchange for scrubbing out an oven and re-organising a food pantry for a couple that were having a baby soon.

It didn’t stop there! Before long she was taking up hems, sewing on buttons and doing basic mending in exchange for garden maintenance and mowing lawns. These guys are ripping up old items from homes every day with their trades so these days they even search around to find her the cheapest - or even free - items if she needs them, as well as providing an oven door and dials on her heater for free. They often come across things that others could use but end up in the tip instead.

As a pensioner, Mum has time on her hands and is very experienced in household chores but has a limited income. This trade of skills and services means she can now carry out tasks within her ability and has made some fantastic friends. Her place looks amazing and is she even happy to do babysitting for the families. In turn they really appreciate having a cuddly grandmother figure around. She has a new purpose and a whole new social network too - in fact she looks 10 years younger!

My home-made Enjo-style floor mop is a joy to use and cost me just $6.00 compared to the brand name alternative! I had been hearing about the wonders of the Enjo cleaning cloths and mops for some time, but the price tag always stopped me from buying one!

Using a hint from the Vault, I purchased half a metre of quality polar fleece for $6.00 and cut it into eight decent sized cleaning cloths, they worked great. Then I looked at my sad sponge mop. It was in a terrible state and the sponge needed replacing - so I decided to try and make my own Enjo-style mop head!

I took one of the cloths I had cut and stitched some elastic around the edges. I now had a removable mop head, and with a little vinegar and eucalyptus I had a sparkling floor. Now every time I mop the floor, I just rinsed out the cloth, dry and replace!

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.

My husband was dying of lung cancer. He wanted his ashes scattered at sea and, being a practical man, discussed other details. He did not think much of church services and a eulogy delivered by a person he did not know.

He died in my arms at home and the next morning he was picked up by Sommerville Funerals. (Most people are unaware that they may have some time with their loved one before the body is collected.) A private cremation was arranged and I collected my husband's ashes for his 'celebration of life' at our home. All our friends arrived, charged their glasses, sat or stood on our front lawn and listened to his story that I had written a few days before. We played his favourite music and people stayed all day. My husband loved a great party and this was no exception. Everyone said this was the best service they had ever attended and they were going to do the same.

Incidentally, the only cost was the private cremation fee. Nothing like some of the very high fees I was quoted.

Instead of paying for one expensive doona, and the dry cleaning costs that come with it, buy two or three cheap doonas, pin them together at the corners, and put them into the same doona cover.

Because cheap doonas are thinner, you can wash them one at a time in your washing machine, and you can also adjust the warmth. When the weather starts getting warmer, just take one doona out of the cover and put it away in the cupboard.

No more dashing to the shops to grab something for dinner when the cupboards are bare! I have discovered a great website to help make the best use of the food you already have in your fridge and pantry cupboard. It is (www.cookingbynumbers.com)

It gives you a list of ingredients and you tick what foodstuffs you have at home on the list, then it comes up with a range of recipes using those ingredients. It is amazing just how much you can make with what is already available to you! It saves on wastage and on buying extra ingredients.

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!
