If it were not for the fact I need it to fly at other club fields and the up comming Warbirds over Dane I would tell AMA to put their membership where the sun don't shine.
If for some reason doing it on the website as described by Dr1 Driver is unpalatable and if the Warbirds over Dane event is an sanctioned AMA event Then you could just ask for the contest director and say "Hi I would like to join the AMA as a new member". CD's are empowered to accept the money and sign you up for instant membership. It makes no differance as to what type of event it is. They can do this only on the dates of the sanction.
