Storing payment info is a in that there are all sorts of Very Serious Security Requirements to taking credit card payments, and some of them are easily sidestepped by not storing any sort of payment information. This is not just me being paranoid, but would also represent new costs as there is separation required from the rest of the servers. Maybe making browser autocomplete work with our form would be a good step? Then you could save payment info in your browser and use it on the site more easily, without adding the burden of securely storing payment info to our backend.
