I think Kogan is "grey market". Nothing wrong with that as long as you're aware before you buy. May find the invoice/bill etc is from his Chinese/Hong Kong company etc? Warranty may mean having to get it back to the manufacturer yourself etc. Don't get me wrong - no need for red flags, am all for parallel importing etc and have bought stuff off him before (including expensive Senheisser headphones and Canon camera) - just realise that it's not an Aussie Bricks and Mortar store
