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!

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!

My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

I have decided I want a house which I can clean in minutes and I don't want any more energy or money draining clutter that makes it harder to control. The more I have the harder it is to control and the more motivation I need to contain it. 'Less is more' is my new mantra! I am applying this principle to my finances as well - when I buy too much it is such a burden and I don't have the motivation to stay on top of all the bills. Therefore, less is more - more energy, more money and more happiness!

I only need to shop for food once a month and am saving $3000 per year on feeding our family of six.

With four children, I was spending at least $800 per month on shopping, so I came up with a plan to try and cut costs. I went through recipe books and chose meals that I was going to cook for dinner. I wrote a list on an A4 page for every day of that month and what I was going to cook for each day. Then, on another page I wrote all the food items that I needed for the recipes I had pre-chosen and that was my shopping list for the month.

The best thing is I now knew what I was cooking every day, without walking to the fridge and thinking 'what am I cooking?' I also put the A4 page of what we were having for dinner on the fridge and the family knew what we were having each day without asking me!

To start with I went shopping every fortnight for food, but now I do it once a month and only spend $550 each month.

Before I began this routine, I was spending $9600 per year on food for four children and two adults - now I am spending $6600 per year! The extra $3000 we save each year goes into our children's bank account, which they just love!

Use this one basic mix to make scones, scrolls, pikelets, pancakes and waffles! It will save you heaps of time and heaps more money!

SUPER BAKE-ANYTHING MIX:

In a large Tupperware container, mix:

2 kg packet SR flour

2 tbs + 1 tsp salt

1/3 cup + 1 tbs + 1 tsp sugar.

SCONES:

In bowl, add two cups baking mix. Rub in 2 tbs butter until mixture looks like breadcrumbs. Stir in 3/4 to 1 cup of milk, until moist but not too sticky. Don't overmix. Roll lightly and cut into shapes with biscuit cutter. Place on lightly floured baking sheet. Bake 10-12 minutes until golden.

SCROLLS:

Complete mixture as for scones. Roll out with rolling pin until 1 cm thick. Spread with softened butter, 1/2 cup brown sugar and a little cinnamon. Roll up tightly from long edge. Cut scrolls into 2 cm slices. Bake on baking tray 10-12 minutes.

Variations: Use your favourite jam or make pizza scrolls using tomato paste, ham & cheese.

PIKELETS/PANCAKES/WAFFLES:

To two cups of mix, add one egg, 1+ cups of milk, 1 tbs oil. Beat together until thick but slightly runny. Makes small pikelets, large pancakes or waffles.

I came up with a great low cost, low stress way to feed the crowds at my son's 21st birthday party. With the weather being chillier, the food needed to be warming and more robust than usual. I came up with the idea of a crockpot party! I am borrowing family members' and friends' crockpots and am filling them in the morning with different dishes, then I can 'forget' about them until the evening! When it's time for everyone to eat, I can then just plug them all into a power board and put them on the table. This is a triple whammy saver for me! It saves time as I don't have to spend all day in the kitchen and can get other things ready for the party instead. It saves money as I can use cheaper cuts of meat to achieve tender dishes and - as I don't have to use serving dishes, it even saves on washing up!

I was usually a pretty prudent shopper but was always looking at the money I saved as potential cash for more purchases. This meant that in the long run I didn't really save anything and ended up with a heap of things I didn't really need.

I started taking a 'savings purse' with me to the supermarket when I did my grocery shopping. Instead of buying the product I would normally have bought, I would choose the cheaper alternative. For example, I would purchase the 'home brand' biscuits for $1.00 less. That $1.00 would go into my head as a saving. At the end of that shopping trip I would put any 'savings' into the savings purse. I was stunned. After two weeks of shopping and 'saving' this way, my savings purse contained $100.

I began to use my savings purse in other ways. If I managed to refuel my car with cheaper fuel, I would put the difference in the purse. If I wanted a chocolate bar, and I resisted buying it, I would put that money in my savings purse. Even with those small amounts, the savings became huge. Doing this began to be fun; it was a challenge to find extra ways to put money into my savings purse!

To top it all off, not only was I saving money but, by 'resisting' the sweets and chips so that I could put the money into my purse, I was also eating healthier and losing weight. I am so happy with the results.

I wanted to share this excellent method for cleaning your oven.
 
Heat your oven to 250C and place two casserole dishes filled with water on each oven rung. Leave for one hour, ensuring the casserole dishes do not boil dry. Turn oven off, remove dishes and let the oven cool for a few minutes. Remove rungs, then wipe oven clean with a soft cloth. The rungs may need a light rub with a Scotchbrite cloth.
 
The new cloth I used was black in no time but my oven was sparkling clean without the use of chemicals, and only for the cost of heating the oven! An impending visit from the oven repair man motivated me to clean the oven. He commented on how sparkling clean it was – he even wrote down the cleaning instructions!

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!
