You should provide as much detail as you can about the item, such as what condition it's in, an asking price, its manufacturer or model, unique identifying numbers, and so on. It's also important to include one or more pieces of contact information, so that anyone who wants to buy what you're selling can get in touch with you. Finally, you may want to provide some pictures, too, so that people can see what your item looks like.
As we mentioned in the opening paragraph of this article, Craigslist leaves the details of a transaction between a buyer and a seller up to them to hash out. This is why, in the previous tip, we said that it's extremely important to include contact information for prospective buyers to reach you at. The default is email (and Craigslist will partially anonymize your email address to help keep people from sending you junk mail), but you can also provide a phone number.
You can even add some location data, if you want to meet (this is useful if the item is stored somewhere other than where you live). However, just be careful about revealing more personal information than you're comfortable with!
Once you've worked out the details with the buyer, you should ask them to meet you in person in order to pick up the item and make the payment. You can, of course, ship the item to them once they've paid you (or have them pay you later), but we would suggest completing the deal face-to-face if possible.
The reason for this is that most deals that go bad on Craigslist do so when people don't meet face-to-face, instead solely working out the details over emails, phone calls, or text messages. Our Is Craigslist Safe guide has more information about that.
