Payments are securely handled by our partner FastSpring.
You can safely pay using PayPal or a credit card (Visa, MasterCard, etc).
Here you can find some of the possible reasons for the cases when a credit card is declined while you are trying to make a purchase via a FastSpring payment platform:

  • 1) Invalid credit card number or billing address was entered.
  • 2) Incorrect or expired credit card expiration date.
  • 3) A hold has been placed on the account. This happens sometimes when the credit card company detects a transaction they don’t believe fits your normal buying pattern and are concerned that it might be a fraud or a charge that you didn't authorize.
  • 4) A restriction may have been placed on the account. For example, the account may be set up to not be used outside the country in which the card was issued.
  • 5) Insufficient funds on the credit card.
  • 6) The amount exceeds the limit set for daily or internet purchases.

If your credit card is declined again after that you have checked all data is correct, you should try to call your bank (credit card issuer) to inquire about further details and see if they can help you understand why your credit card failed to make the payment.
