On December 17, Xiaomi opened a registration window for customers interested in purchasing the Redmi 1S for Rs. 5,999 at a flash sale on Flipkart.

Flipkart is an e-commerce website in India offering online shopping for gadgets, books, clothing and other products at good prices. Flash sales allow customers to register at a given time before the product becomes available. This kind of sales allows products to sell out in seconds.
