Have been tracking this one for a while and this is the cheapest I have seen it so far.
Also available for $567.99(Standard Bundle) from the Insta 360 official website. Incase you choose to traverse down this path you get rewarded with an complimentary Insta 360 flask for shelling out $10 extra bucks. It doesn't have cameras though what a bummer.
I will be waiting it out until Black Friday/Christmas time as I don't believe any action camera is worth more than $500 but if you need one immediately for your upcoming trip this is a good deal to consider.
Was 491.99 during mobileciti 25% off sale on ebay. Could price match this one at anaconda if your local has stock though.
