Berry nice savings to be had on blueberries!

I have found the answer to enjoying the health benefits of blueberries is in the freezer aisle! Blueberries are so good for you, but very expensive if you buy the punnets of fresh fruit. The regular price of fresh ones works out at well over $30 per kilo and while they look nice on a fruit platter, they don't have a lot of flavour. Instead, I now buy frozen blueberries at around $4 or $5 per 500g pack - less than a third the price! Simply throw a cupful in the microwave with a teaspoon of sugar and zap for a minute or two. Much tastier and are delicious with ice cream, natural yoghurt or just on their own!

Make every cake of soap last twice as long

To make a cake of soap last twice as long, simply paint the top or bottom with some PVA wood glue and let dry. Doing this means only one side of the soap dissolves, enabling the cake to last double the time. I paint the top side of the cakes of soap when we bring them home. Sometimes my granddaughter even glues a pretty picture to the side!

$21 Challenge helps two families

I took on the $21 Challenge, and won! However, my husband was a rather grumpy participant; he loved the savings but not the lifestyle during Challenge week. As he goes away regularly, I decided that every night he's not home for dinner would become a $21 Challenge night for the kids and I - all meals must be made from ingredients I already have at home, and I can only use ingredients that have not been allocated for other meals. This saves money and gives me a night off cooking, as my Challenge meals are usually simple affairs, sometimes as easy as pancakes or toasted sandwiches.

The true value of the $21 Challenge became apparent when a friend was recently diagnosed with a severe form of leukaemia. She is a married mother of four boys and is embarking on a long therapeutic journey that will hopefully lead to a full recovery. As a way of helping her family, the parents at our school have banded together to make all their meals for the next three to six months. As they are a large family, with an above average food requirement, I was unsure how I could afford to help feed them each week. Thankfully, my husband was away the week my friend was diagnosed, so the kids and I lived off the $21 Challenge that week and all leftover money was put into making meals to freeze for my friend's family.

We now do the same thing whenever my husband is away – it's a great gift over the Christmas break to know that I can afford to cook and freeze meals for my friend's family, and look after my family at the same time. Thank you.

Use it or lose it

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.
