I have odered some books from flipkart on 23/12/2016.
I got delivery on 25/12/2016 which is one day before the promised day.So they really have fast delivery.
The product quality was good and the books were brand new and there were not any defect.
Their app is awesome and it has lot of options which makes the shopping easy and effective.
Their website us also good but I like app better.
The colustomer service is also good and very responsive. You can contact them easily by using the toll free number and they will give you appropriate solution in a pleasing way.
I think Realibility of this site is good and the product it deliveres are guenuine and authentic with good condition.
