Arlo Pro 2 2 Camera Kit $699 or 4 Camera Kit for $1,199 + Bonus Arlo Pro 2 Camera + Free Upgrade to The Premier Plan for 1 Year
Bonus camera essentially making it a 3 (VMS4330P) or 5 camera kit.
Didn't charge me for delivery at checkout so I assume it's free delivery. Don't need to be an existing RACV member to purchase.
Still had bonus cameras in stock when I called up this morning.
I was looking at this, this morning. Seems like a good price. 3 camera kit is about $850 based off price hipster etc. + the premium subscription (though probably not necessary for my use case.)
I called up just now and the sales person assured me there was plenty of stock for the bonus camera.
Ask for sales to get to someone who knows about this, unless you want to spend 20 mins getting bounced around to someone who knows anything about this.
