Free domains..

[.amaZe]

Does anyone know how to set up your system to enable free domains like this..

 

I offer free domains to my clients if they purchase a year's worth of web hosting. But, at the same time I also I have coupons/promotions I run.

 

Is it possible to not allow the coupon to be used if a client wants to purchase a hosting account yearly to get the free domain, and to also take advantage of the discount yearly.

 

Lets say:

1. Plan A costs $50 a year.

2. Discount B is worth 50% off your first payment.

3. Client C wants to buy Plan A yearly, to receive the free domain, and he also wants to use the coupon.

4. In the end Client C, will be paying $25 for first payment and getting a free domain.

 

Is it possible to exclude the coupon from being used on yearly accounts, and still allow the client to get the free domain? Because If I don't do it this way, he will end up paying less and I will lose profit.

 

Instead of getting $50 from the client (minus) domain registration fee. I will end up with $25 (minus) domain registration fee.
