Scams when selling on Craigslist or ebay

I occasionally sell (or attempt to sell) things on CL. Simply put, as soon as you see "is your item still for sale?" immediately delete that email and do not reply.

Edit: I should also add, don't give out your phone number until you're sure you're dealing with a real buyer. That is, unless you like having your number distributed to scammers and Indian telemarketing centers.
