My past experience with Flipkart is good. Specially when I ordered my Acer net-book, which was delivered within 48 hours of placing the order.
However, I happen to order a Pack of 3 Denim Deo's, which took an astonishing 6 days to be delivered, which according to me is a lot of time. Considering the speed at which today's eRetailers can get it shipped within 2 or 3 days.
And it was from WS Retail.
It varies from the logistic partner they use to ship. For the netbook, they delivered it via Bluedart, but for the Denim Deo's, they shipped it from eKart Logistics (never heard that name before, so don't know that could be the reason for delay of delivery)
