Yes, but the rules also say that someone is supposed to make contact within 3 days, either the bidder or the seller. I had this happen to me once. Buyer purchased with BIN, and then I could not make contact with them. 3 days went by, and still no contact. I began sending emails. I informed them that if there was a problem or reason for delay to please let me know, so that we could work something out. I then informed them that it also states in the rules that it is their responsibility to make sure that they can get to a computer, such as at the local library, to make contact. Finally, when I still had recieved no contact, I informed them that should they not pay by the 7th day, that I would have no choice but to report them as a deadbeat bidder. On the 7th day, I recieved payment via Paypal. Never a response from this seller, and no feedback either....which was okay with me. It was very weird.
