So in a couple of categories in my directory, I have the following need:   - 14 day free plan - 1 month free plan - 2 months free plan - 3 months free plan (default plan) - 4 months free plan   The reason for this is that this a pet adoption listing. I don't want the listings to get old when the owner doesn't come back and remove their listing. The user will have a good idea of how long they are willing to list their animal for adoption. Some will be short, some will be long.
