Adding posts to a subscription

[Hornstar]

I had a look for this and im sure ive seen it b4 but cant find it now.

I have some subscriptions that people can buy on the site, but I want to give them a bonus, so each time they renew there subscription they get 50 extra posts. Or whatever I set it too.

Is this currently possible, or do i need a hack to do this, and if so does anyone know how to do it.

Thanks

I don't understand the question. How are you limiting post counts currently for a paid subscription? I see a timeframe limit on subscriptions, but not a post count.
