Reposted from my comments in a previous thread regarding Craigslist:
Don't Ship, Don't Ship, Don't Ship, Don't Ship, and finally - DON'T SHIP!!!!
I have made hundreds of Craigslist transactions (buying and selling) and never had a problem. I have meet lots of great people and even had some repeat sales of photo gear to people that I met on CL. I am no expert, but here is the quick guide:
I don't even respond to email's that start out: "is your item still available?" I include my cell number to my response, and if I can't speak to a live person within 2 to 3 emails - move on to another buyer.
Craigslist is a cash marketplace - don't accept Credit cards, PayPal, Money Orders, Western Union, Escrow, Bank Transfers, IOU's, or anything else but good old genuine American Cash Dollars. Don't waste your time communicating with anyone who doesn't understand this concept.
Never meet at your home - don't give out home address or your home phone. I have a throwaway email account for CL. Don't use your email if it is firstname.lastname@example.org. I would not use my work email, but that is up to you.
Pick a very public meeting spot. Starbucks is my favorite. Don't be afraid to walk if you feel uneasy - trust your Spidysense: if you hear a voice telling you something is not right, then listen to the voice.
If you are buying or selling a high ticket item, meet at your bank - (or the buyers bank), or the local Police Station. (If you are selling at a bank - deposit the money or get a Money Order - don't walk out with cash).
Finally, be safe. Nothing is worth your personal safety. A simple Google of Craigslist robberies will give you hundreds of hits. All most all, will be situations were the victim did not use common sense.
Good luck (and don't forget ---- DON'T SHIP!!!).
