Watching my 'non-Simple Savings' sister unpack her groceries this week made me realise how much my shopping habits have changed in the year since I discovered Simple Savings. I used to love supermarket shopping, wandering the aisles for hours, one of this, one of that.

Some products I just don't buy anymore include:

• Liquid handsoap - I now make my own (my first SS project from the Vault). Saves $40/year.

• Spray and cooking oil - I buy 4L of good olive oil on special for about $20 and use a refillable hand pumped spray container (from House, $15 - will last years). I used to buy cans of olive oil spray at about $3.50 each and by changing how I buy oil, I am saving $100 per year.

• Cleaning products - are now missing from my list - we use bi-carb and vinegar and other simple Vault tips.

• Dishwashing cleaner - has gone too. We use citric acid, which I normally keep for my yearly lemon cordial making.

• Soft drinks and cordials - are rarely bought now - we use juice as you would cordial, and have changed our habits in favour of water.

• Yoghurt - we make EasiYo using packets bought in bulk from GoldenGlow online. Saves about $150 a year.

• Eggs and vegies - in the back yard!

• Condensed milk, Yogo, cake and pancake mixes - we M.O.O. ('make our own') using Vault tips.

• Icypoles - M.O.O. using tinned fruit juice or other - search the Vault!

• Magazines - I never buy new, just pick up the free supermarket recipe brochures or occasionally buy some gardening ones from the op shop.

• Junk and pre-prepared foods - we buy a lot less in favour of having our own 'sausage roll make-athons' or other baking with the kids.

As well as noticing the presence of many of the above things in my sister's shopping, I also noticed she buys small quantities of lots of items I now buy in bulk. Each week she has to mentally or physically check if she 'needs another of...', where I buy large amounts from the supermarket and other cheaper sources - and then don't need to think about it again for at least six months. These types of products include:

Washing powder (I'll never buy less than 20kg, and with the Vault advice to reduce our amount per load, this is lasting ages!), teabags, coffee, shampoo, dog and chook food (from pet supplier every six months), ham and meats(buy large piece of ham and store in ham bag per Vault tip - saves at least $50 a year over my previous habit of buying little cute packets of 50g each), bacon (buy from ALDI and freeze), dishwashing powder (ALDI brand is MUCH cheaper than the Finish tablets we were using - saves us $150 a year at least. I buy 12 months supply on one of my ALDI runs), cheese (buy larger amounts less often and freeze if necessary), rice (10kg bag much cheaper), jelly crystals (I bought 5kg bag at IGA last week - makes 20 serves for same cost as three individual packets), tinned fruit, soup, tomatoes and other products (from SPC outlet), nappies, paper towel and toilet paper (I buy lots when on a fabulous special). Fruit and veg I buy from the greengrocer, the market or grow my own. Meat is from the butcher, chicken from the poultry shop and fish from the fishmonger once every three months.

I could go on for every grocery item - nearly everything has changed in 12 months. This is even without noting the savings from changing products - for example, I used to think myself very clever if I bought my Uncle Toby's quick oats on super special for $2.00 per kg box - until I discovered I can buy Home Brand, which I cannot fault, for $1.00 a kilo all the time. Same for most basic products.

With changes like these to my grocery shop and to our home loan, insurance, shopping habits and so on, Simple Savings has saved us thousands of dollars in our first year of membership. Our lifestyle has actually been RICHER since SS. I didn't set out to change my shopping habits - I just started by making handsoap and buying Home Brand porridge oats - but suddenly I have realised how large this change has been. If I see you at the supermarket with your milk, bread, 8 large packets of toilet paper, 6kg of the super special meat, 10kg of rice and three-litre containers of vinegar, I'll know you caught the bug too!

Want to freeze cream without it becoming a watery mess once it's defrosted? The secret is to whip it before you freeze it. Defrost it naturally and you would never have known it was frozen.

This method lets me buy brand name cream when it’s on sale, usually as it's reaching its use by date. I whip it up, portion it off into 100ml containers and throw it in the freezer. I no longer have to worry about buying a full container of cream, then trying to think of how to use it all up before it reaches its expiry date. No more waste!

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

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!

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!

Changing circumstances and a growing familly all added up to us paying a whole lot less off our mortgage than we would have liked. Pretty soon we would have started to go backwards. It was crunch time!

Using the Simple Savings calendar I identified our most expensive habits, and was astounded to see the amount of money that could have been saved. Our grocery bill was always around $200 or more per week. This amount did not include meat or bread that we get from the butchers and bakery.The trouble was, my husband loved all the expensive name brands for items such as chocolate biscuits, lollies and savoury snacks and was convinced that the cheaper or no name products would be tastless and boring. Week after week I would just automatically reach for these items, without even glancing at the alternatives. I knew as soon as my husband saw the packaging, the goods would remain in the pantry unopened, and he would then go and buy the brand name items anyway.

One week I kept mentioning to him that I was going to do a big clean up of the pantry and I was finally going to utilise all those assorted Tuppaware containers that I had never used. That week I substituted his expensive brand of snack foods with cheaper versions, emptied them into the assorted airtight containers and threw the plain packaging out before he could see them!

I also applied this technique to several other items; I would fill cheaper dishwashing liquid into Morning Fresh bottles, no-name hand wash into saved Palmolive dispensers, you get the picture. Our grocery bill went down from $200 to $140 per week - a saving of $240 a month!

When I finally fessed up to what I had been doing, my husband admitted that most of the snacks were just as good as the name brands, you just have to try a few out. All it took was some creative (OK, and somewhat deceitful) way to present the changes, but we have never looked back. Why would we, with a saving of $3120 a year? Plus of course, one very neat pantry!

Making your own pizzas is a brilliant way to save money on buying them - but I bet you haven't tried this! You can save even more money on takeaway pizzas by making your own bases using just TWO ingredients!

This recipe makes two medium sized pizza bases:

2 cups self raising flour

1 x 200g tub natural yoghurt

Simply combine your two ingredients in a bowl and mix together until well combined. Turn out onto a floured board or surface. Knead together as usual, then divide into two equal parts. Roll out your pizza bases, add your chosen toppings and pop into the oven for 15 minutes at 220 degrees.

The results are so delicious. Simply use up whatever you have in the fridge to top your pizza and you've got a super cheap and filling meal. I've converted all my family and friends too! I dare you to give it a go, you'll be amazed!

I am saving an amazing $100 a year on home-made pancakes! My family love it when I make pancakes for them but being a typical time-poor mum, I only ever made the 'instant' type in the plastic bottles. The trouble is that one bottle only lasts one pancake making session, so not only is it costly but I would also have liked to have enough be able to make extras for lunches and so on.

Then I recently stayed with a friend who was making up this Bulk Pancake Mix to put in a breakfast hamper for her elderly dad. She kindly shared the recipe with me and now our family gets to save $100 per year and we also contribute around 75 less plastic bottles a year to landfill too!

Bulk Pancake Mix (Makes 7 - 10 pancakes):

6 cups plain flour
2 tablespoons baking powder
1 teaspoon salt
1 cup milk powder
3 tablespoons sugar

Method:

Mix together the following lightly -

1 1/2 cups pancake mix
3/4 cup water
1 egg
2 tablespoons oil

Cook in a non-stick frypan over a medium-high heat. No more 'plastic bottle pancakes' for us!

I loved my friend's idea of bagging it up for a present too. She was putting hers in a large plastic ziplock bag, wrapped in brown paper and tied with a gingham ribbon, with a bright red cup measure and the instructions tied to the top - very cute!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

I am a young woman on a single income, paying off my homeloan. I know the amazing financial savings that are possible when you make extra payments of any size on a large loan. However, because I am on a low annual income I often find it very hard to find any spare cash after all the bills have been paid.

So for birthdays and Christmas, when my friends and family are seeking ideas for gifts to give me, instead of asking for things I don't really need, I ask them to deposit the amount that they would have spent on a gift straight on to my homeloan. I am very close with my friends and family and they understand my financial situation. They are only too happy to help me get ahead and hopefully one day own my own home. It is a gift that keeps giving and one I truly appreciate. I read recently that for every extra $1.00 you are able to pay against the principal of your homeloan you will save $2.00 in return and take years off your loan. The understanding and generosity of my friends will help save me tens of thousands in interest over the years.
