Craigslist and Ebay are both amazing online market places. Ebay is a for profit company that charges sellers to post their ad in front of a global market. Whereas Craigslist is a non-profit organization the generally connects local sellers with local buyers, similar to newspaper classifieds.
Each website has its advantages over the other. Craigslist is typically my first avenue when selling because it’s free to list, I get paid immediately, and I do not have to deal with a shipping company (big hassle). Ebay is nice because I get connected to a larger audience and I do not have to physically meet up with a stranger (see my article on tips for meeting people on Craigslist).
Hard to ship things such as cars, furniture, homes etc. are ideal candidates for Craigslist. It’s not realistic to sell and ship a couch across state lines. I’ve found Craigslist to be a great tool to sell common items such as ipods, electronics, furniture, and text books and not so great at rear items like antiques, my faceplate off my stolen stereo, or specialty car parts. With Ebay’s global audience, it’s much easier to find that handful of people interested in a right tail light off a 1980 Camaro than it is with Craigslist’s local viewers.
