I just heard from one of the conference coordinators - the non-discounted price, which will be available on 3/1 to anyone (you do not have to be an official ICAN member to go to the conference, but as I mentioned in the last post, you do have to be a member to be eligible for pre-registration and discount) will be $249.
It's worth it to become a member - you do get added bonuses such as quarterly issues of The Clarion (with the latest in cesarean news and birthing rights updates), and discounts at the ICAN Bookstore. And those who chose professional subscriptions also get a listing on the ICAN website as a supporter.
