Please list newspapers and/or magazines that have national (U.S.)
circulation and that offer free, low-cost, or introductory trials
rates for classified or other advertising. The publications should
reach general or business readerships such as those of the New York
Times, Wall Street Journal, Investor's Business Daily and be suitable
for advertising a service business.
An introductory trial offer could entail, for example, a minimial cost
for the first runs in order to assess the usefulness of running the ad
over a long term. References to specific publications and low-cost
rates are more important than background, secondary sources, and
discussion.
