If your payment was declined, it may be due to one of the following reasons:

• You exceeded your card limit. Confirm the card has enough funds available (either check your account balance or contact American Express), or try another card.
  
• You entered a typo in the payment details or card expiration date. Verify you entered accurate information.
• You entered an unsupported payment method. Check on the payment page whether your payment method is accepted.
• American Express couldn't authorize your transaction due to a technical glitch. Contact us or try again.
• American Express noticed a charge that doesn't fit your normal spending pattern and blocked the transaction to protect you. Contact us for help.
