I had a non-paying bidder for one of my auctions who kept promising that they were going to pay but never did. Finally, when I went to file an Unpaid Item Dispute, I saw that they were no longer a registered eBay member, so I was able to get a final value fee credit and relist credit. I relisted the item. Now the same person has won my relisted item using a new eBay ID with zero feedback. I emailed the person to tell them that if payment is not received within my listed timeframe (3 days and I only accept PayPal), I will have to file a dispute. This irks me that this same person has won my auction and I probably won't receive payment again.
