The Paderno Spiralizer is the number 1 rated spiral vegetable cutter on Cook's Illustrated Equipment Reviews. https://www.cooksillustrated.com/equipment_reviews/1676-spir…. They're used for making vege noodles and other "pasta" as well as sweet potato curly fries.
It's usually $50 on in Australia; it's USD 47.36 on Amazon https://www.amazon.com/gp/product/B0007Y9WHQ/, delivered to Aust (so no bargain).
I picked up one in the Chatswood store for $25 - that's 50% off. It doesn't appear to be on special on their web site.
Please note: the 3-blade ones are on the counter. The ones on the shelves are the 4 blade unit https://www.amazon.com/dp/B00AW3B5MM, which simply is not as good as the 3 blade unit (as well as being more expensive) - check the reviews.
Amazing deal OP! I bought this for $60 AUD off Amazon and still worth every penny. I might pick up another if I find myself in Chatswood.
