Well, I have placed many orders from Flipkart in the past and, surprisingly I have always received them on or before the tentative delivery date mentioned in the email, considering where I live, i.e. Gangtok.
In a recent event, when one particular order could not be fulfilled by the seller, the amount was refunded to my account in a matter of few days. Therefore, I am quite satisfied with the overall processing and delivery by the online retailer.
However, I have never placed any order for electronic goods and most of the complaints seem to be regarding this kind of items. I cannot seem to be able to take a risk to order expensive or electronic items.
