Specifically, we do not know whether the credit card ends up on your server (possibly stored poorly), and just knowing you use Stripe (which allows for that not to happen) doesn't guarantee that your server has the requisite security required to not have been modified to send the things we enter to a third party.
(That said, I will say that I am not actually the kind of person who fears using my credit card online, so I may be simulating this argument train incorrectly; these thoughts go through my head, but my reasons for often using PayPal when provided the option have more to do with liking the kinds of reporting I can easily do using their APIs.)
One thing I absolutely wanted in our new system was that we were never going to store the cc# - that's one of the reasons I liked Paypal/GC because we never stored the cc number. I read something about a wine store being hacked and the hackers getting all of the credit card numbers recently.
(Honestly, and I realize this is a stupid bias on my part, I'd trust your site more if the labels on the text boxes lined up with text boxes. I think it is fair to say, however, that a lot of people have silly biases like that, as a lot of time you are just fighting with some gut feeling someone is getting about your site as they are about to convert, and not any appeal to rational argument.)
(Again, though: I am actually the kind of person who tends to just use their credit card willy nilly. I, personally, would have no serious problem signing up for your site as is. However, if you had PayPal as a payment option, I'd use it, and in the end it could actually save you money. If you had Amazon Flexible Payments as a payment option I'd definitely use it, and it would almost certainly save you money.)
As for Amazon, I spoke with them at length - their FPS service won't work for us they said.
Thanks so much for your feedback
