As expected Oneplus announced a price cut for OnePlus One. Earlier they have done a flash sale from June 1 to 7 and later a permanent price cut of $50 which was not available in India. On the same thread where they announced the flash sale they informed a user from India that Indian users also will get a price drop soon.
This offer is only available for the 64GB version of OnePlus One (Black), you can get INR 2000 Off on this product just for one day, June 18, 2015, that is tomorrow. you can get the phone for just INR 19,998. They announced this on their Facebook page.
What we believe is that OnePlus will make this price drop permanent later as they will be announcing OnePlus Two next month. OnePlus already started teasing the OnePlus Two images and also they are conducting contests too.
