When you reach the checkout page, your membership invoice will display the chapters in a 50 mile radius according to your zip code. If more than 1 chapter displays, delete the chapter(s) you do not want to join from your cart and leave only the one chapter you wish to join.
If you would like to join a chapter other than the one that pulled according to your zip code, please call the member services department at 888-557-2266 or 847-375-4733 to have the chapter of your choice manually added to your membership account and delete all chapters from your cart at this time.
