Xiaomi Mi3 Flipkart Sale : Log
On contacting Flipkart support, they denied shipping faster and also said that I'll have to wait for delivery.
UPDATE: August 30,2014
It took 4 days for the Mi3 to reach my doorstep, It was delivered before the expected delivery time but I'm still disappointed with Flipkart, they didn't provide faster shipping offers on this device and some people reported that the device reached them in 1 day even after using the standard delivery option (Yes, they do live in Mumbai)
Anyways, I'm still happy with their service as the customer support was kind enough to help me and provided me with the package status, every time I got in touch with them.
