eBay and Craigslist are becoming such a hassle nowadays that I usually don't bother. However, I've had good luck listing my duplicates on a trade thread. I traded about 75% of my duplicates a few weeks ago and I ended up with some really good games that I didn’t have in my collection. All the trades were with TCP members so I know they went to good homes and we didn’t have to screw around with any eBay fees. Technically, you don’t have as much protection if someone tries to screw you, but I was only dealing with people that have been members for a while, plus I wasn’t dealing with any high dollar games, so the risk was pretty minimal for me. If you have duplicates of high value games, that’s sort of a different story.
