you sold the card on the 10th and posted this thread on the 17th. you have to wait 4 days till you can file non payng bidder alert and then he has 4 days to pay after that. so he had till 16:53:39 PDT today to pay for the item at least. you should have finished the deal when he paid not refund him. when the npb dispute closes he cant leave feedback, so shows dispute was still open.
