The price for each spot announcement is $450 for radio and $150 for newspaper as long as the minimum guaranteed number is exceeded.

The second spot plan is for during the 5-day work week and has no radio spots/week and five newspaper spots/week. These plans are also available on holidays but not at an extra discounted rate.
