I understand that you can block bidders, and cancel bids on auctions if someone's feedback is questionable (ie: lots of 'not received' and unnecessary negative feedback left), but what protection is there against BIN sales?
From what I understand if I refund a buyer's $, and refuse to ship, they can not only leave negative feedback, but also file a claim against me for non-performance? So it seems my only recourse is to ship them the item, and pray I'm an exception to their scam &/or negative feedback trend? Then be ready to file a claim with insurance 45 days later? It mostly concerns over-seas sales, as it costs so much to ship packages with tracking, and that's where many of my more expensive items head (and if I charge for tracking, nothing would sell, there's too many US sellers that can ship for cheaply/Can sellers offering the same item via small packet). If I paid the extra for tracking out of pocket, I would lose money on the transaction.
So my question would be, does eBay offer protection against the BIN seller's right to refuse service? I searched the help files, but could only find the blocked bidders list, canceling bids, etc (so obviously they understand there are some undesirable purchasers).
