Booktopia's free shipping promo code will get you this book for $17.50 delivered. The code expires midnight, so if you don't get it today, you'll have to wait for their next free shipping promo code (which I'm guessing will be around Valentine's Day).
SPIRALISE! - Delicious Meals to Make with your Spiraliser - includes a selection of Pete Evan's recipes which you can make with spiralised veggies and fruit. This book sells on an average of $22.50 delivered, so you're saving 25% off market prices. Although the next best price I could find at QBD isn't far off at $17.99 with free delivery, over at The Nile, Fishpond, Boomerang Books and Angus & Robertson (which is now merged with Bookworld) you would be looking at paying between $22 and $28 for this same book delivered.
I've been wanting to buy both a spiraliser and a book with recipe ideas since my friend told me about the aubergine pasta they've been making at home. Spiralisers are very in at the moment, offering people a way to increase their vegetable intake by replacing traditional pasta and noodles with veggie noodles.
