medpal : The automatic item receipt confirmation happens only when the seller uses
PowerShip, a new initiative from eBay for sellers, where eBay will handle the logistics and has tie up with BlueDart and Fedex. So once the seller marks the item as ready to ship, eBay arranges pickup of the item and complete tracking is available on eBay itself. This is somewhat like the 'Fulfilled by Amazon' service. You will still be able to raise an item not as described or any such dispute like before.
As a seller it is good, as 95% of the time the buyer forgets or don't give much importance to confirming the item receipt even when he has received the item well before the deadline and is happy. I faced this problem many times while I was selling few items on eBay and had to wait 7-10 days after the product was delivered for the item to be confirmed by the system and my payment to be released.
