I always shop from online and from many sites like PAYTM, snapdeal, Amazon, Ebay, etc but I recommend for new buyer(one who buy first time from online) always use flipkart to get trusted products from excellent supplier.
It’s return policy is too good and have easy refund within 24 hours but one thing is that it is a premium shopping site and charges extra compare to the other sites.
I was purchases one of the biggest site in the world and return product but get refund after 15 days and always need to complaint about refund, according to my experience is giving that flipkart.com is too good.
