I'm looking for best practices for keeping track of who I send Christmas cards to - I'd like to use the Contacts app if possible. One thought is to create a Group and drag contacts to it. Another approach would be to create a smart group, and have it search for text within individual cards "Holiday Card". But - How do I handle one household with multiple contacts (husband and wife for example)? I'd like the count of Contacts in the Group to help me with how many cards to order - so should be de-duped by Household.
