This is similar to the deal posted in February, except this is slightly more expensive. Still one of the cheapest prices around, though. No expiry date was mentioned, just 'Only for a limited time'. AU stock and warranty.
What I don't really understand is how they manage to get so many refurbished units they can stock them as a semi-regular item. Where do they find them all?

Probably from DJI Care, you pay a insurance type fee when you purchase and it covers you for 2 crashes - even total destruction as long as you can send them the bits and they replace for a fixed fee
