I entered my credit card info and it failed. I rechecked my info and submitted again and failed again.
I finally, decided to pay with Paypal and it was approved.
Pretty disturbing to think how many people try to order with their CC and when it errors out they just leave without going to Paypal.
I would think that a lot of people who don't have Paypal are not going to bother to sign up for it and will just leave.
Come on ClickBank get your act together.
