Craigslist selling - part 2

A few weeks ago I posted how great this site was and how nice it worked to sell our old bath vanity. Well, a few other items I've posted have not had the same luck. What bugs me is the people who send "tell me more about your item" emails, even though I post a phone number and ask buyers to call for more info. Some folks I get into an email discussion with suddenly stop responding. They make it sound like they want the item, and are ready to rush right out to get it. Then I loose contact and never hear back, even after a few more tries of "are you still interested" emails. Sure would be courteous if they would just respond with "sorry, I'm no longer interested". My other issue is it seems many buyers are lazy, and do not search for what they are looking for. So if an item is not freshly posted in the last day or so, it falls down into no mans land, where few buyers will find it. Case in point, I've now posted my desk for sale twice. Each time I've gotten about 3-4 "hits" right away via email. But after a few days, all buyers fall silent. This tells me people are most active on new items at the top of the list, and tend not to go to the site searching for a particular item in mind. So, in my experience, selling on Craigslist is hit or miss, takes persistence and patience, and may not always be worth the time involved trying to sell something.
