The payment methods available to you are displayed during checkout according to your location, device, order, and the payment services available to the store.

Please select an available payment method and follow the instructions presented during checkout to complete your order.

We take reasonable measures to support the security of information submitted through the checkout process.

Payment processing may involve third-party payment service providers. These providers process transaction information according to their own security and privacy practices.

• Payment information is submitted through the checkout process.
• Sensitive payment credentials should not be sent to us through ordinary email or social media messages.
• Customers should use only the official yickoi™ checkout when placing an order.
• Customers should keep their own payment accounts and authentication information secure.

Payment is generally authorized or processed as part of the checkout process when you place an order.

Your bank or payment provider may display a pending authorization before the transaction is fully completed. The timing of these records can vary between financial institutions.

If you see a pending amount that appears unusual, we recommend checking with your payment provider first while also keeping your order confirmation available for reference.

A payment may be declined for a number of reasons, including incorrect payment information, insufficient available funds, bank restrictions, security checks, or issues determined by the payment provider.

If your payment does not go through, please check the details entered during checkout and, where appropriate, try another available payment method.

• Confirm that the billing information is correct.
• Check that your card or payment account is active.
• Confirm that your payment provider has not blocked the transaction.
• Try an alternative payment method shown at checkout.

In some cases, your bank or payment provider may temporarily display multiple pending authorizations when a transaction is retried or interrupted.

A pending authorization does not necessarily mean that you have been charged multiple times. The final status is determined by the payment provider.

If you believe that the same order has resulted in an actual duplicate charge, please contact us with your order number and relevant transaction information so the situation can be reviewed.

After a successful order, an order confirmation may be sent to the email address provided during checkout.

Please keep your order confirmation for your records. If you completed payment but did not receive an order confirmation, check your spam or promotional folders before contacting our support team.

When a refund is approved according to the applicable return and refund conditions, the refund is generally sent through the original payment method where possible.

Once a refund has been initiated, the time required for the amount to appear in your account can depend on your bank, card issuer, or payment provider.

For questions about whether your order qualifies for a refund, please refer to the Return & Refund Policy or contact our customer support team.

Customers should take reasonable precautions when using online payment services.

• Do not share your card security code or account password with other people.
• Do not send complete payment credentials through email, messaging services, or social media.
• Review your order total and shipping information before submitting payment.
• Contact your financial institution promptly if you notice suspicious activity on your payment account.

If you have a question about an order payment, an unexpected payment status, a refund, or another transaction-related issue, please contact our customer support team.

To help us review the issue efficiently, please include your order number and a brief description of what happened.
