Amazon a great trusted online shopping site.
From amazon I bought some items like pendrives, watch , mobile phones etc
And the service and delivery done by amazon is very appreciable and fast.
Comparing to other online shopping portals like shopclues and snapdeal where sometimes they deliver froudulent items to the customer and no further return policies at all.
But in tne case of amazon faster delivery and customer service like return policy, customer supports etc are very nice.
Amazone prime membership give me early acces to the items on flashsale during the grat indian festivel sales.
So in my opinion amazon is the best choice for u to purchase or sell items easily and secure.
