Can I post my ad on more than one craigslist site?
Please choose just ONE local craigslist site for which your ad is most relevant—generally the site closest to you. If your ad is equally relevant to all locations, your ad does not belong on craigslist. Please find another service. Posting the same ad to multiple locations on craigslist is prohibited.
