Try using PayPal as an alternative. Even if you don’t have a PayPal account, you can still use this option to pay with your credit card. PayPal supports credit card transactions without requiring an account. Alternatively, you can try a different browser.

If your card is declined, it’s important to know that these authorization errors come from the bank that issued your card and can be caused by a variety of factors including inaccurate details, lack of sufficient funds or missing approval for international transactions.

In some cases, it might be due to the autofill function which many browsers and phones support these days. Try entering your card numbers manually to resolve this issue.

You can contact your bank for more information about why the card was declined.
