The OnePlus 3 launch event is scheduled on June 14th 2016 (this month), however much before the launch i.e. on June 6th, about 1000 OnePlus 3 units will go on flash sale, unfortunately only in China. For the flash sale the OP3 price is RMB 2999 (Rs. 30K approx).
Now the OnePlus 3 price for the special flash sale is not the official price, it will be lower than that. The price will be disclosed on the launch date itself i.e. on 14th. Those who manage to buy the OnePlus 3 in the flash sale for RMB 2999 will get free replacement insurance for broken screen for 6 months and CNY 249 bonus gifts.
You can watch the launch event live as it happens in VR, yes you will need a VR headset, in case you don’t have one you can try getting the Loop VR headset for Rs. 1. The OnePlus 3 launch event will begin at 10:00AM Indian standard time on 14th.
