RCA J2C ConditionalProducts is the Pro enforcement layer for J2Commerce shops that sell gated add-ons. You define which qualifying products unlock which dependents. The J2Commerce plugin enforces those rules in cart and checkout, and an optional system plugin can keep OS Services Booking closed until the shopper qualifies. RCA J2C Storefront can show the lock on catalog cards. This package makes the lock real at checkout, not just styling.
Use the menu under RCA J2C ConditionalProducts Docs for overview, quick start, install and updates, requirements, configuration, how-to guides, frontend, integrations, troubleshooting, FAQ, changelog, and support.
