Thanks for the suggestion. I'll keep tweaking it. I'm seeing fewer (actually, none) bounces off the payment page than before, which suggests that the change I made has already helped.
I'm limited by a serious lack of graphic design skill, and this page wasn't part of Primate's original design work for the site. It shows. :-) It will get a proper design at some point in the future.
perhaps an additional field: Email: [_____________] Confirm Email: [________________] Subscription: $24.95/Month (after free 7-day trial)
I tend to be suspicious when the price isn't at least as conspicuous as the biggest/boldest text.
