The Big Picture Of Package Eligibility Rules
The packages described under Examples of Campaigns and Packages have a variety of eligibility rules. Designing these rules can be easy or time-consuming; it all depends on the complexity of your business rules. We'll walk you through several examples to help you form an intuitive understanding of how to setup eligibility rules. Once you've acquired this intuition you'll be ready to design the eligibility rules for your own packages.
Don't confuse package eligibility rules with those associated with a campaign. Package eligibility rules control whether a customer is allowed to choose a package on the order transaction. Campaign eligibility rules control whether a campaign is highlighted on the "eligible campaigns" content zone and on an order's eligibility tree.
