Amazon is one of my favourite website , after shopping from flipkart i bought product from it. it's very easy to buy product and like other top websites it also has an official application . which makes ordering online very easy. Other than this amazon delivery is also very fast in most of the product . which gives it plus point. i have bought 8 products from amazon in 6 months and never faced any problem , i didn't used it's return feature because there was no requirement for it so can't say about it.but other than this amazon is really a very nice website . you will not face any difficulty. Plus the product are genuine and quality is superb. Few items are available at amazon at heavy discount , and it's a real discounted items , unlike other sites mrp is not increased and then discount is shown . so just try it without any second thoughts.
I will definately recommend you all to buy product from amazon, you will love it and will not regret your decision . just go for it. i am sure if you will buy once then will surely use it again later. :)
