A cheaper deal than the 159 asking price of the newer Instant Pot Duo Nova's which are being sold for $159 by Amazon AU. Worth considering if you don't need the latest and greatest. From what I can tell, the main differences between the two are fewer automatic cooking modes as well there being no automatic sealing lid for the Instant Pot Duo. Additionally a UK cable is supplied so you either need a plug adaptor or to use a standard AU kettle/PC cord instead.
Not the absolute cheapest base price compared to the past Amazon deals but it's close and it's arguably cheaper if you manage to squeeze in the 15% cashback coupon from shopback that's expiring soon (https://www.ozbargain.com.au/node/632381)
Not as good as $68
