PayPal uses a complex screening process for credit card payments. This helps prevent fraudulent transactions. On rare occasions, the screening process affects valid cards.
If you have another card you could try that.
Or you could try resubmitting your order another day.
You can resubmit unpaid orders by going to your Form-A-Lines account orders.
Another way to solve the problem is to sign up for a PayPal account. It is free and only takes a few minutes. You can then link your card to your PayPal account to ensure a swift checkout experience. PayPal is a secure way of shopping on millions of websites worldwide because of PayPal Purchase Protection.
We regret we don’t have any other method of taking payments.
