First listing and winner was an international bidder even though I specifically said I wouldn't ship overseas. My mistake as I didn't block international bidders in my auction. Anyhow, winner claims they lost their credit card and was waiting on the bank to issue another one....whatever. So I relisted and this time the winning bidder has ZERO feedback. Contacted buyer via email and sent invoice...Natta, nothing, zip. Is there a way to block people from bidding with zero feedback? Maybe third time is a charm.
