Bryan sorry to hear of your troubles. I am really hoping to avoid the same thing.
I recently sold an item on eBay and the seller asked me to cancel the transaction because their bid was an accident. I PMed back and asked how they bid on accident. A man PMed back and said his wife bid on the item and he didn't need it.
So still being a smart a$$ I said I did not know how to cancel an auction because I had never done it before. Then I asked if he had canceled auctions in the past and if so could he tell me how to do it.
With in a half hour I received payment for the item and it was delivered a couple days ago. Haven't heard anything back from them and hope I don't.
