"If I pay with my debit card, is there an extra fee?
In the United States only, Adobe may process debit card payments as PIN-less debit transactions for your subscription. This means that although PIN-less Debit payment transaction will be processed like a PIN-debit transaction, you don't need to enter your Personal Identification Number (PIN).
Your financial institution may charge you a fee for payments we process as a PIN-less debit transaction. If you have any questions regarding the terms and conditions of your debit card, contact your financial institution using the telephone number found on the back of your card."
