I presume Wireless 1 eBay store is matching JB HiFi's deal at the moment. Can get an extra 5% off with eBay plus membership. I personally own this phone and can't fault it at all!
Extra 2% off if purchasing using ZIP google pay option - $664.05 - 2% (max $30 in one transaction I believe) = $650.76
Get in quick before they sell out if you are in the market for a phone.
I have eBay Plus and it's showing $699 for me before selecting ZIP google pay.
