Subscription as reward for referrals

I'd like to encourage my customers to bring in referrals: get a 1-month premium subscription if you bring X customers that sign for the basic subscription (or whatever). Or even: get a 12-month premium subscription if you bring X customers that keep their subscriptions for 3 months.

Is this possible? Ideally, subscriptions awarded would expire automatically.

Define referrals please.

You might be able to do this with CB Invites plugin an CBSubs promotions plugin.

This is what I have in mind:

Customer A has a basic subscription. We give her a referral link like "domain.com/subscribe.php?refid=customer_A" that she can send to her friends. If X friends purchase a basic subscription through that link, customer A gets 1 month of premium subscription for free. After that month, she goes back (automatically) to the basic subscription.

Even better:

Customer A has a basic subscription. We give her the same referral link as above. If X friends purchase a basic subscription through that link *and* each of them keeps that subscription for 3 months, customer A gets 3 months of premium subscription for free. After 3 months, she goes back (automatically) to the basic subscription.

The only referral system supported is iDevAffiliate and PostAffiliatePro. We've no referral system built into CBSubs to allow purchase of subscriptions or anything of the sort with those referrals, sorry. Best approach is to use one of the above and provide "superficial" payouts; meaning it's fake currency that you can allow them to redeem towards subscriptions (you'd need to do this manually).
