The weekend I tried to sell 3 plasma TVs: FOBO vs. Craigslist vs. Amazon

The only things I've sold on Amazon are textbooks (no real local market unless you're lucky). I've bought and sold cars, furniture, electronics, and a lot of other stuff on Craigslist. Everyone I've interacted with in person has been normal and friendly. Fielding multiple no-reply emails is the most frustrating part.
As a general rule when selling, if someone's email has terrible grammar and sentence structure I'm going to just delete it. If someone is polite and asks about the item and then leaves their phone number I'll most likely respond. As for the price, people will always haggle so I will automatically set the price to $20 over what I want get from it, then they feel like they get a "deal".
Similarly with buying, if they can't describe the item coherently I just ignore the ad.
Getting things off CL is a much more passive experience than playing the role as provider of the goods.
I have sold a TV via eBay's Valet service and loved the experience!
