Keep the straws from unwanted drink bottles

If you have a drink bottle with an internal straw, when the bottle cracks, leaks or dies, don't throw the straw out! Remove it from the bottle and keep it in your cutlery drawer for whenever you need a straw, or keep a couple in your bag for use when you're out. I keep three in a little cotton bag in my handbag for when we order a drink that would normally come with a disposable straw (milkshakes, iced coffees, spiders, soft drinks). After use, I just give the straw a quick rinse in the restroom sink, or wrap in a serviette, and give a good wash when I get home. A simple way to reduce waste and help the planet!

Make your own nut butters for a fraction of shop prices

I save a fortune on buying nut butters by making my own. Almond butter, cashew butter and good quality peanut butter can be fairly expensive to buy so instead I buy roasted almonds for about $4 at a bulk supplier (Bin Inn if you're in NZ) and blend it in my Nutribullet with the addition of a smidgeon of olive oil. This gives me twice the quantity of a shop-bought jar which would cost at least $12! You can also add a little honey or chia seeds to add variety. I use the same method to make cashew butter. I simply buy 200g of cashews for $4.80 from an Indian grocer, roast them in the oven and blend them with the addition of a little olive oil to start the process. At around $15 a jar to buy at health food stores, this is a terrific saving!

Cheap toddler food at the shops

I've found a really cheap and nutritious way of feeding my toddler when we are out shopping. Most of the shopping centres around us have a food hall and most of them have a roast carvery type place (that sells roast meat, chips, vegetables and so on).

At the carvery, I ask for a bowl of peas, beans and carrots for my baby. Some places have given it to me for free, commenting how nice it is to see children eating vegetables. Other places will charge $0.50c and the most I have ever paid is $1.00 for a 'big' baby sized bowl full. Don't forget to ask if you are buying a roast meal there yourself, because they may throw in a baby sized bowl free.

It's great when I run out of food at the shops, if he eats everything I have taken with us, or if I've taken longer shopping than planned - it's really healthy and cheaper than buying baby food in jars (which my toddler refuses to eat anyway). We have been doing this since he was eating finger foods from around 12 months old. When he was small he used to eat one pea at a time, which provided hours of entertainment too!

There are other vegetables available but we avoid any that have been fried or cooked in oils (like roast potato) and those that have sauces (like cauliflower cheese).

'Grandma's Day' saves $30 a week on groceries

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!
