Recently I purchased a used hand plane on ebay. I paid for it immediately and was informed that I'd have the plane October 3rd. I wasn't in any particular rush for the plane but when October 10th rolled around I thought I should contact the vendor to see if the plane had been lost. I was told that he hadn't shipped it because he'd, "...ran out of boxes and was waiting for a new shipment." Really, I wouldn't have minded if he'd had the courtesy to email me and tell me that shipping was going to be delayed but I felt it was pretty crummy for him to have both my money and the plane. I put in a complaint to ebay and they refunded my money and I received the plane the following day. when I didn't IMMEDIATELY send him the money, the vendor started threatening me with mail fraud! I did pay him after I'd sat on his money for a week or so and I think he got the message.
This is the only problem I've ever had with a buyer or seller on ebay. I'm wondering what the rest of you would have done.
