Almost every community has a local paper. The interesting thing that people don’t know is that the community papers typically all belong to their states press association. Through this association, you can place a classified ad that will run in every single newspaper in that state. In most cases, the cost of running an ad in every single community paper is less than running one ad in your local major newspaper.
To find your states press association, just do a search for “Illinois (or whatever state) press association” or “Illinois (or whatever state) newspaper association” on Google. Most of the time the association’s website will come up within the first 2 pages of results.
Within their website, they should list the total circulation (number of subscribers), a list of participating newspapers and their pricing structure.
