Seems like a lot of online stores are selling this cheaper, here are a few:
https://www.dicksmith.com.au/da/buy/lenovo-legion-go-z1-extr… (sold directly by Dick Smith and not a third party - note presale and delivery dates)
Same for Kogan, sold directly by them (pre-sale) - Lenovo Legion Go Z1 Extreme (512GB) https://www.kogan.com/au/buy/lenovo-legion-go-z1-extreme-512…
Amazon ($200 discount coupon can be applied): https://www.amazon.com.au/Lenovo-Legion-Extreme-Gaming-Conso…
There are a few others like WiseMarket as well but never heard of them so not posting the link.
JB Hi-fi - I tried to price-match with JB-Hi-Fi - the best they could offer was $1399, basically $100 off & they quoted the others are likely 'grey' import & don't have the warranty like they do.
Anyway, this is my first post by the way, I'm just sharing what I've found as I've been monitoring the price of this for a number of weeks now hoping it would go down in price. Tempted to go with either DickSmith or Reebeloo. Never bought anything from Reebeloo but for an extra $99 they provide a 2-yr accidental & breakage coverage which includes liquid damage, not sure if anyone can share this exp with Reebeloo pls?
