Amazon.in is the no.1 online shopping site . I personally mostly shop on amazon and every time I purchase products over there is awesome experience .the service provide by them is simply awesome . product quality is amazing they only ship what we see on site. delivery time is also quiet good they deliver before 1-2 days commence shipping date . I didn’t use there app because I mostly on laptop and shop through there sites which is very easy to navigate.customer service is also good if we refund something within 3-4 days they refund us .overall it is best online shopping site.!
