I usually shop from all online shopping portals whether it is flipkart, snapdeal or amazon.
The best in the trio in my opinion is amazon.
For different people it may be different as all the people live in different different states.
I live in UP and I guess most of the people in the state will go for amazon only.
The reason behind it is that flipkart is not delivering here for the last one year and snapdeal too sometimes shows problem in delivering.
Well the site is nice,
App needs some improvement.
The delivery persons carry swipe machines through which we can pay by cards.
Overall, the service is nice
