I current offer hosting pricing monthly, semi-annual, annually, biennially, and triennially. I'd like to include some products or services with my hosting packages, but only if they purchase at least 1 year. Maybe 2 years for premier services. I've created an add-on, and associated it with one of my hosting packages. It shows up in the cart, but it's available for any billing cycle. Any way to make this happen? Thanks!
