Braun Series 7 (720-4) electric shaver for $322 from Fishpond.com.au (possibly $222 with $100 cashback offer)
But, Braun are also running a $100 cashback promo on purchases of the Series 7 range until 15th of April. See details here: http://braun.com/medialib/downloads/anz/promotions/braun-cash-back-2013.pdf
Main text on the offer says "available from participating stores" however the terms only stipulate that it needs to be purchased between 1st March 2013 and 15th April 2013 as well as being one of the "participating products" (i.e. from the Series 7, 5, or 3 product range).
To be on the safe side though, I'd avoid buying from auction sites like eBay. But if you can end up getting this shaver for $222, that's a great bargain.
