Flipkart used to give better service before. I remember receiving items within 3-4 working days. The service times have now deteriorated drastically. You will have to wait for 8-10 days for the delivery.
Also, it seems they have changed their business model to more like E-Bay, where other independent sellers deliver the goods instead of Flipkart itself. Still however the goods are genuine.
(Unlike Ebay where most of the goods are Chinese duplicate- especially computer parts). So, in short, better than Ebay, but going the Ebay way.
