Nope - never been duped on eBay, but I minimize the chance of that happening by merely skipping the deals that appear to be riskier than others for the amount of $$$ that I'm saving. I buy a LOT of travel-related material on eBay (a majority of the $20k), but I'm not going to give a complete stranger control over my flight plans just to save $20.

Dollar-denominated hotel gift certificates are another story - I am an infinite buyer at 75-80 cents on the dollar, and there are a lot of people selling into that price range.
