I regularly shop online. In the case of ebay, couriers very rarely deliver the goods before the last possible day, sometimes even later, though the tracking details show that the item is already in Goa. This despite the seller shipping immediately. In contrast, couriers deliver Flipkart, Snapdeal etc consignments immediately.
This issue needs to be resolved, else customers like me who have been with eBay for more than 10 years will be forced to shift.
