I have been using Amazon app for 5 years now and by for it is the best online shopping app in terms of service delivery it’s bang on and I have tried other app like flipkart they were not as good as Amazon so I would recommend everyone to go for Amazon for online shopping these reason for choosing this: -
It’s quality is best and delivery in time and more these things I bought my camera just three month ago then I got delivered in just 7 days and camera quality is soo good
