The experience on amazon is just life made easier and faster. I want to give a simple example I booked Sony Xperia x dual in flipkart on 29th lune 2017 and booked its case in amazon on 1st july 2017. The phone’s origin was just nearby my house and the case was getting shipped from Ned Delhi.
But the amazing thing is I got the case 2 hours before the phone which was booked two days before the case!
