Half the RRP. Must be a stuff up on JB Hifis end, they are listing both the XB60 and XB90 under red hot deals for $429 and $349 respectively.
If anyone wants the GTK-XB60 you could try to get JB to price match The Warehouses price of $349.98.
good price for the Sony GTK-XB90, last cheapest ever price on pricespy was $496. So for $349 that's a great deal.
oddly the smaller speaker GTK-XB60 at jbhifi is more expensive.
Get Noel leeming to pricematch online if available and then use code "app" to get delivered for $1.
