RCA Conditional Products is the Pro enforcement layer for J2Commerce shops that sell gated add-ons. You define which qualifying products unlock which dependents. The J2Commerce plugin refuses cart and checkout lines that break your rules. An optional system plugin can keep OS Services Booking closed until the shopper qualifies. RCA Storefront can show the lock on catalog cards. This package makes the lock real at checkout, not just pretty CSS.
