I think the regular price is $179/year. In the past there have been discounts but I havn't seen any for a while.
But... I'm with you. I can't find the info anywhere on site. Try this; http://www.guitartricks.com/trial_splash.php . It's from the GT YouTube site. For me, it takes me to my account page but it might treat you as someone new.
Good luck.
