Sock it to draughts with cheap 'door snakes'

With every winter, it's important to make our heating systems as efficient as possible. Draughts under doors (both to outside and to rooms not currently being used) let heat escape, driving heating costs up. Door snakes are often advertised at around $10 each. This means for a whole house you may be looking close to $100. Instead, you can use a pair of men's long, knee-high socks! These can be filled with rice (or sand if you have easy access to it). Either tie a knot or see the top to seal. You can purchase ind the socks at cheap shops or ok shops, use the cheapest rice you can buy and you can make a house-full for less than the price of one commercially produced door snake.

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!

Only cook once a month

My husband and I have become '30 Day Gourmets' and enjoy both the savings and the extra time we spend together as a result! We recently looked into 'Once a Month Cooking', which we were interested in because neither of us really enjoys cooking tea when all we really feel like doing is relaxing after being at work.

After gathering ideas of how the scheme works (literally - you cook once a month!), we thought we would try it by cooking for a fortnight first. We gathered recipes from the Internet and raided the recipe books (the recipe must be able to be frozen) and came up with such things as marinated chicken, curried sausages, spaghetti sauce, apricot chicken and all kinds of things.

We then picked a Sunday, turned up the stereo and did nothing but cook! It turned out to be a really enjoyable day. Once cooked and cooled, the food is put into freezer bags or takeaway containers (which cost almost nothing) and frozen. What we thought would last two weeks actually lasted three!

Each night, I would take out a container or bag for the next night and leave to defrost in the fridge. We then dragged out the steamer, threw in all the vegetables and once a week cooked up a big pot of rice. We would then have a small portion of meat (which also lowers fat-intake levels), have a pile of yummy steamed vegies and a little rice - the result being full bellies, smiling faces and very minimal washing up!

This not only saved us money but also time. Usually groceries cost us $150 for two weeks. With the cost of buying meat and grocery items needed for the cook-up ($100) and in-between buyings of vegetables once a week ($10), we spent a total of $130 when we would have spent over $150. (This is because at each shop we would grab things we liked, but didn't really need). Having a selection of meals already cooked for the weeks ahead feels great!

At first a big cook-up seems difficult if you aren't motivated, but you can start small and next time you are cooking something that would freeze well, cook double or triple the recipe and freeze excess. I also went to the local library and got out some books on freezer cooking which also had suitable recipes in them.

My husband and I honestly can't believe how we survived before our cook-ups and love the idea of actually doing things we want to each night, rather than being a slave to the kitchen!

NB - A book from the library which was a big help in planning recipes was 'The Freezer Cooking Manual from 30 Day Gourmet'. The '30 Day Gourmet' book is available on eBay and from most bookstores.

One tablespoon only per wash

Slash your washing powder costs by using a tablespoon of washing powder in your machine instead of a scoop. It works just as well! My sister was learning about budgeting and the speaker mentioned that you could get the same wash results by using one flat tablespoon of washing powder as you could if you used a whole scoop. I decided to test this theory and found that even with a full load of washing this proved to be true. I buy a top brand washing powder that costs around $10 per two kilo box and it contains around 148 tablespoons. I used to go through a two kilo box of powder every four to six weeks when I was using a scoop. Generally I do a load of washing every second day, so using one tablespoon per wash, my box of washing powder should now last me nearly 10 months! Just changing this small habit will save me $90 every 10 months on washing powder!
