I'm quite obsessed on one page checkout using drupal commerce kickstart. I'm using commerce coupon(wonderful module) and we all know that there's a possibility that the order total price could be zero if you we apply a 100% coupon module. I see this post Commerce - how to set no payment for free orders when 100% coupon applied and I guess we are having the same problem. I did not see any way to ajax refresh the payment method pane, and my last work around is to reload the entire page after applying coupons.
Is there a way to reload the entire page after applying coupons?
Thanks.
