Xiaomi had released their flagship phone Mi3 in August 2014. The phone, sold for Rs 13,999, had specs which were usually found in phones twice its price range. Flipkart put it on a flash sale and over 20,000 phones were sold in a few seconds. The site also crashed in the process. The Flipkart site crashed for the first time when Moto E went on sale on May 14, 2014. It had also received flak for the sale of Moto G which were sold out in 40 minutes when it went on sale for the first time in February this year. Of course, Flipkart has only improved its sales timing since then.
