In my 7+ years of eBay experience, I have never had anything like this happen. I only ship with in the U.S., and I have my eBay settings fixed to block bidders from countries to which I do not ship. I had a lot of books that a buyer in the Philippines (sp?) wanted. He said he had a sister in the U.S. that the books would be shipped to. I opened the settings on that one auction to let him bid. Big mistake!
The sister contacted me wanting my mailing address. I wrote her back and told her I only accept Paypal payments. The buyer emailed me and asked me to make an exception and accept a check from him. I said OK. Mistake #2.
I waited 2 weeks, and I didn't receive the payment. I filed a non-paying bidder dispute with ebay. The buyer never answered the dispute so I closed it after 8 days, and I received a FVC. I also left the buyer neg fb stating I waited 25 days for payment, but it was never received. I put the books in my store, and a buyer came along in less than an hour and purchased them.
Yesterday, the non-paying bidder contacted me, and said he would be sending payment right away. I wrote back and told him that he didn't answer the unpaid item dispute so I closed it and re-listed the books. I told him the books had been purchased by someone else and were no longer available.
Today, his sister wrote me an email saying that she mailed a check yesterday as soon as her brother contacted her about the negative strike against him. She said my address was confusing.
She also told me to remove the neg strike against him. 
Dh said I need to just ignore the emails and IF something does come with either one of their names on it, take it to the post office and return to sender.
I'm just wondering what other sellers in my position would do. I feel bad ignoring them (even though I gave them every opportunity to pay), but it seems as if communicating with them is only making the situation worse.

) That would have been fine if the people who asked for quotes were bidding, but they weren't. I'd say probably only 1 out of 50 international shipping quotes would generate a bid.
