Valid only for today, Flipkart is offering Xiaomi's budget offering, the Redmi 1s on sale without the hassle of pre-registrations. This is the final sale of the Redmi 1S and Xiaomi has restricted it for only one day. Ever since Xiaomi started selling its smartphones in India, they have been notoriously famous for their flash sales. The sales require pre-registration and even after doing that, there is no guarantee that you will be able to buy a phone as it solely depends on the availibilty of the stocks. Some sales have even seen the phones selling out in a matter of seconds. The Xiaomi Redmi 1S was announced back in July at the launch of the Xiaomi Mi3 in India. Note that this is the final sale of the Redmi 1S, which means that it could very well be discontinued just like the Mi3 was earlier. The company has grown to become the third largest smartphone manufacturer in the world just on the heels of Samsung and Apple. The company recently announced the Xiaomi Redmi Note (3G and 4G versions) and is focused on selling that device right now. The Redmi Note went on its first sale on December 2, with the next sale scheduled for tomorrow. You will need to register for it, which can be done through this link. Xiaomi has also slashed prices of its 10400 mAh power bank to 899/- for Flipkart App Users.
