Since the price is calcualed using the Amazon Currency Converter, the price might come out better depending on how you choose to pay.
I know this is only $2ish difference from the deal from ShoppingSquare. Though, I've heard good stories about Amazon service and ShoppingSquare stock is direct import product from overseas warehouse.

Hah you beat me to it. Just spotted the price reduction in my cart. Better than AU pricing.
