Google Nest Audio Chalk colour only discounted $149 down to $129. Works out to be 2 for $258, so cheaper than the 2 for $268 deal if you're after a set to use for stereo pair / multiple rooms.. Don't forget discounted gift cards or Price Beat at Officeworks if you don't have access to discounted GC's.
Edit: looks like they’ve changed the price for charcoal as well to $129.
Also both OW and Bunnings were quick to change their prices this morning so no good for price beat.
Edit 2: Harvey Norman selling for $128 so another potential price match - I managed to get them from Bunnings but be quick.
