The default ClassiPress membership option allows unlimited ads for a time frame and price determined by you, but if you're looking to allow only some free ads you may need to look at allowing coupons for this in the form of the
AppThemes coupons plugin. There is no functionality built into the theme which will allow only some free ads and the rest paid unless they pick between specific ad packages (free or paid), but there is nothing which would prevent continuing to use the free ad pack. Thanks.
