EDIT: Amazon AU just lowered their prices to be in-line with amazon US. Since prime works here, it works out about $5 cheaper. Especially if you use shopback and there's also the ability to use amazon au gift cards (but not promotional credit).

It does work out cheaper than the other deal through amazon AU, I just bought two of these bad boys. If you're buying more than one be sure to order separately or you'll end up spending more due to import fees on-top of GST.
