1. To use a credit card, ignore the first section... look for the "or" (indicated by my little arrow).

2a. In the top part of this screen "Pay with debit or credit card", fill in all the required fields (as indicated by my little arrows):
2b. In the bottom part, fill in the remaing required fields (indicated by my little arrows).
Then turn off the "Save info & create your PayPal account" option (as shown - Big Arrow 1).
Then click "Pay now as guest" (Big Arrow 2).
PayPal will process your card payment and return you to the Books And Records site.
