Buy Now buttons bypass our cart and take buyers directly to instant checkout for just one item at a time. PayPal Pro requires that if you're going to offer the buyer a card-based Direct Payment checkout option at all, before checkout they must also be given the option to pay with a PayPal account. Thus, we cannot create a Buy Now button that would use the card-based Direct Payment checkout method, but if you have PayPal Pro you can still get Buy Now buttons that would use a PayPal Standard checkout.
