More annoying eBay buying experiences

Recently, I’ve experienced far more sellers suddenly refusing to ship a watch after winning an eBay auction. Just within the last month I’ve had three sellers back out after winning and paying on their auctions. Seller’s remorse..who knows? Their reasons for doing so are always nebulous if not comical: “I don’t know the process of shipping a watch”, watch suddenly broken, etc. Since many of us purchase (and sell on eBay) maybe it’s worthwhile to start a thread reviewing these unscrupulous “sellers”.
