I have tried flipcart, ebay and amazon.i find amazon is a step ahead then this two.amazon services are good compare to other stores. The delivery is up to date and faster delivery is also an good option. And now amazon have exchange offer to like flipcart. The only thing I want amazon to change is the app design and interface. Means its very simple. If we compare apps design. Flipcart app design is pretty impressive
I dont have any complaint with flipcart or ebay. But one time my one product ordered from ebay is delivered 4 late.
