weird eBay product

The first time I tried to sell something on eBay was a fairly memorably (traumatic) experience. I thought I was so smart (I was 19) and that everybody else who was already on eBay was just silly and that they were selling their items well below market value.  What I later learned was that eBay is market value, and those books that claim how much stuff is worth are just plain wrong.   I even recently learned about a product called eBay Crusher that can help you make money on without even selling anything.  I realize that sounds bass ackwards to anybody who has sold on eBay before, but it’s weird how well it actually works.
