Craiglist is an anonymous Internet forum that you can use to buy and sell products and services. For best use, visit the Craiglist home page and select the area nearest you. From there, you can search for services or click the "Post to Classifieds" button to make your own post.
When posting your own classified, the Craiglist website guides you through a classification process to ensure your post is categorized appropriately where potential buyers can find it. Craiglist also asks for contact information. If you wish to remain anonymous, avoid listing a name or phone number, and select the "CL mail relay" option. This option masks your email address, allowing you to receive responses to your offer while preventing spammers from sending you email.
Once you find someone who wants to buy your product or service, set up a meeting place and time with this person. While the vast majority of Craiglist deals occur without incident, stay safe and be aware of possible scams. Request to meet in a public location, and don't accept payments through money order or cashier check. If you are making a high-value purchase or sale, consider arranging the meet up at your local police station.
