I think NY does qualify for the incentive program. CT does not.
However, your referral has to mention your name at the very initial point of contact with DVC. If they sent for the video 3 years ago, they are already in the system. DVC usually does ask a new person "how did you hear about us" or "do you know someone who owns DVC" to give them a chance to say a name. If they don't -- no referral bonus possible.
