I used to sell a wholesale list & business guide for pocket bikes/minibikes.. I had a picture of the damn CD on the auction, said 17 times (I counted) that it was a cd, and I even posted all of the questions I received to the auction, so by the time I stopped selling them, my listings had over 30 specific instances of me saying "you are buying a cd, not a motorcycle"... you'd think at least the $3 shipping fee would have tipped them off.... but no, I still got at least one comment per day asking stupid sh*t like "how fast does it go?" or "can I ride it on the grass?"
I made a few hundred dollars, but honestly... the frustration wasn't worth it. Given the time I spent dealing with the idiots on there, I would have made more money flipping burgers at McDonalds.
I continued to sell lists after that until I got too busy with classes, just not on ebay anymore.. much easier that way.
