>I bought a music box at a garage sale for bout $10. It seemed like a good deal at the time. A few months later I noticed a label on the bottom so I did some research and discovered that the same item was selling for around $1,000 on eBay. Should I now go track the owner down and tell her that she should have asked for more money? You didn't know. It was a trade among equals. This was different. That said, there are some situations where it's considered OK to rip people off. Finance works like that. But I would've thought that museums had slightly higher standards of conduct than Goldman Sachs...
