my big poke on ebay was about 15 years ago, I sold a Craftsman Riding mower, disclosed all that was and could be wrong with it. I guy from Austin TX bought it, paid through paypal, drove up to where I live and picked it up. He was happy as heck with it when he left. About a week later, he filed a claim through ebay, I was puzzled. Anyway, I could not prove that he ever got the tractor, because I did not have any proof that it was shipped. So, he got the tractor and he got his 800.00 back and I got poked.
Now, if there is a local pickup on an item, I still send a letter with tracking on it, and it is proof of delivery. I have had 2 times since, that the proof of delivery through the post office, of a letter with a receipt, showed that the item was delivered and got to keep my money.
Of course, years ago, I had bought some software from someone in New York city, and they sent me a letter, with tracking on it, and nothing else. As they had proof of delivery, I couldn't do anything about it and was out the money.
Some people are such low life’s all I can say is they will get theirs one day karma will return the crap they do to good people
