Waste of time. I sometimes will list something with a ridiculously high price on Craigs List because it's one of those "I don't really want to sell it, but could use the space for something even better if someone takes me up on my offer scenarios". you never know what the actual motives of a given seller are.

If you see a ridiculously high price and are interested in something, it's also not out of line to lowball an offer. I had something listed at $550 a while a go and ended up selling it for $150 because the person on the other end knew what they were talking about and I knew I wouldn't get an annoying email or call in a week asking for a refund because the game doesn't work.
