No Car Wars for me. Frustrating

I have spent the last 15 minutes trying to pledge for the Car Wars kickstarter to no avail. All previous Kick starters I've played with have had a convenient pay with Amazon function, I couldn't find this function for this one. So I attempted to type in my credit card info several times and every time I tried to click the green pledge button nothing happened or the billing address fields vanished. It is very frustrating
