well i think when making a deal, there should be a clarification on warrenty side. i notice some thread has specified no manufacturer warrenty. so that's a good way of specifying. if there is still manufacturer warrenty and seller provides 1 week warrenty. then the seller has the obligation to RMA the card without charges from the buyer. cases where there are no more warrenty from the kilang and personal warrenty from seller. then most likely you have to provide refund.

i think everything has been sort out. its time to close it.
