Spotted this at Booktopia. Apparently March is the "For Dummies" month and they are offering 30% off top 30 bestsellers. Anything from running a Small Business, playing Guitar, Writing Fiction to Raising Chickens.
If you are looking for free eBooks, check out this old thread on many IT-related "For Dummies" books free to download. Also the For Dummies tag and some past freebies are still available.
Remember too if you search for the title on: http://www.booko.com.au and choose Booktopia (instead of using the Booktopia direct link you will get free postage and avoid the $6.50 delivery fee. This works on any title that Booktopia offers!
