flexible discount system

[Realname]

I want to offer such kind of discount:
when customers for 3 months (virtual server), the gets 2 next months for free. Is it possible? If yes, where can I set this discount?

You need to add a new condition: Purchase of service for 3 months.

Unfortunately, BILLmanager doesn't allow you to add a discount for 2 months. But you can give a discount on renewal for 1 or 3 months.
