I was in Aldi today and noticed this desktop water cooler (Lumina brand) for $49. http://www.aldi.com.au/au/html/offers/2827_20265.htm
It looked identical to the Aquaport water cooler I own. For the past couple of months I've been unable to find the filters for this cooler. The normal price for these was $20 each. Low and behold they were selling identical water filters for 6 for $20.
I have confirmed they are the same by comparing the filters. Also you can see from the Aquaport website they sell 3 filters for $30 and also state that these are for the Lumina water cooler.

So now I can buy 6 filters for the same cost as I use to buy one. Bargain!
This is from Aldi's special buys from Wednesday the 28th of December.
Hint: unless you're living in Adelaide, the water you get out of a tap is generally of a quality to match what you'll get out of a filter. Especially since professionals monitor water quality for the town, and most people who use their own filters just don't maintain them to a similar level.
If you live in Adelaide, use a spoon if you want a glass of tap water. It'll provide you with all your nutritional needs in one glass.
