A mix of bugs and suggestions: - It is possible for the security code and card number fields to be green, indicating they have been filled out correctly, using a 3-digit security code for an American Express card number or a 4-digit security code for any other card number. - The security code help probably should not display the American Express case when no card type has been identified. - The security code field should display 4 dots when American Express is detected. - The card type detection is so faint as to be invisible to inattentive users or people with awful displays. - Drop-down for expiration is a disaster and a huge regression from the status quo. I played with the checkout form some and discovered these additional issues: - Email validation is wrong, valid emails are flagged as incorrect. - At almost all reasonable browser widths, the right 2/5 or so of the security code tip is cut off, rendering it useless. - After clicking "Purchase License" without completely filling out the form, the button permanently changes to "Please Correct Errors Above." Correcting the errors will not allow you to actually purchase a license. You will need to refresh and enter all your data again. - You can actually successfully submit the form using a Visa with a 4-digit security code or an American Express with a 3-digit security code. It was declined :( - "The 'exp_month' parameter should be an integer (instead, is MM)." is not a very usable way of phrasing this error. I would not buy $149 closed-source beta software for making my purchase form more usable from people with such an unusable purchase form.
