Solutions to a failed checkout

If you have trouble while completing a payment, kindly consider our suggestions below:

You’re unable to pay with your debit or credit card:

  • Make sure all information is correct including the credit card number, expiration date, CVV code and billing address.
  • Check your credit or debit account balance for available funds.
  • Check whether your card is authorized or the default online transaction limit is too low.
  • Try refreshing the page or logging completely out and then logging back in.
  • Go incognito or use a different browser/device to make the payment.
  • Start over with a new order instead of trying to pay for the same order over again.
  • If your payment is still declined, you may need to contact your bank. As part of security, most credit card companies will automatically block international transactions or payments unless the card holders specifically request the transaction.

You‘re unable to pay with PayPal:

  • Check with PayPal to see if your account has a transaction limit.
  • According to PayPal rules, the shipping address and the billing address must be in the same country, otherwise the payment will be declined.
  • Try to use incognito mode or a different browser/device.
  • If PayPal is still not working, please use your debit or credit card (Visa, MasterCard, Discover, and American Express).
