Well, I am in a situation now where I had paid the seller for two item nov.30th at SF, it took him four days to response back to me , he told me some blank email I sent him, a confirmation # was sent to me, this does not proof he actually sent the item. Now it is Dec 10th, I still have not receive the items, I told the seller that I am very concern, seller told me that he gave it to his mail department at his dorm, maybe they are just too busy and the USPS are also pretty busy over the holiday that I should wait two more days. So I will wait two days. What is my recourse after two days and still have not received the item. can I file a complain with Paypal to recover the money. I know that this apply to item bought on ebay , do SF buyer get similar protection. for item not received. My hope is that the USPS priority mail is slow and I will receive the items tomorrow.
