Amazon is worldwide online shopping store. But flipkart is very good than amazon. Delivery service is good but return policy is not good. Delivery boy should pick up from home when anyone returns the item. Amazon is not user friendly like flipkart and other online shopping stores. Deal of the day is not good. I think it’s a shame. Amazon gives mi 20000 mah power bank just in rs. 250 - 300. Is it true? It’s fake and the power bank is very bad and local. So I suggest you that if your buying anything go to flipkart store. Thank you.
