Sonos Move 2 $538 ($528 via Good Guys Price Beat) + Delivery ($0 C&C) @ Harvey Norman

ATL, I believe. Expires tonight. Same price for white version.

Good Guys (and therefore JB Hi-Fi) will price beat for further $20 cheaper: https://www.thegoodguys.com.au/sonos-move-2-move2au1blk
Using instant 4% discounted gift cards (Macquarie) landed me at $506.88.
