I must live in CloudCuckooLand. I sell and buy on Ebay. Most of my sales are stuff I pick up at yard sales for next to nothing, sell at a bargain price and still make money. A few months ago, I bought a box of old watch parts for $17 and sold it piecemeal for hundreds. One buyer was so embarrassed at the price he paid for what turned out to be rare gold pocket watch parts that he sent me an additionl $20. Keep in mind, I kept a sterling silver watch fob for myself that is listed for $300 on an antique site.
So the guy I bought the stuff from made money, I made money, my buyers made money and we're all happy.
