Amazon.in or Amazon.com is nice websites where you can buy or sale your products.
Whenever I buy products online, I have gone through many websites like flipkart.com, snapdeal.com etc. But the trusty worthy site for me is amazon.in because it provides good quality products, no duplicates, Original once.
As far as service concerned that’s very impressive quality service.
Instant action taken for your complains.
all I can say its a trust worthy site where you can shop and relay on their services.
