When you submit an order, your payment provider may authorize or charge the total amount shown at checkout. An authorization confirms that the selected payment method is valid and sufficient funds are available.

In some cases, your bank may display the authorization as a temporary pending charge before the payment is fully processed. Orders are not confirmed until payment has been successfully authorized or completed.

Product prices are displayed in the currency shown on our website or converted into an available local currency during checkout.

If your payment method uses a different currency, your bank or payment provider may apply:

• Currency conversion rates
• International transaction fees
• Card-issuer processing fees

These charges are determined by your financial institution and are not controlled by crstkin.

Applicable taxes, shipping charges and other available fees will be displayed during checkout.

International orders may be subject to customs duties, import taxes, brokerage fees or local charges that are not collected by our store. Please review our Shipping Policy for additional information.

Our store is hosted on Shopify, and payments are processed through Shopify or selected third-party payment providers.

Payment card information is transmitted using security measures designed to protect data during checkout. crstkin will never ask you to send complete card numbers, passwords or banking credentials by email, phone or contact form.

To help prevent fraud and unauthorized transactions, an order may be selected for additional verification. We may contact you to confirm:

• Your name and billing information
• The email address or phone number associated with the order
• Your authorization to use the selected payment method

We may delay, decline or cancel an order if payment cannot be verified or if we reasonably suspect unauthorized or fraudulent activity.

If a paid order is canceled, the applicable amount will be refunded according to our Return & Refund Policy .

A payment may be declined because of:

• Incorrect billing or card information
• Insufficient available funds
• Card or account restrictions
• Bank security settings
• An unsupported payment method
• Temporary technical or network issues

If payment fails, confirm your information or contact your bank before trying again. You may also select another payment method displayed during checkout.

A failed payment attempt may temporarily appear as a pending authorization, even when an order was not completed. Pending authorizations are normally removed automatically by the bank, but processing times vary.

If you see multiple completed charges for the same order, email us with your full name, order number, charge amount and transaction date. Never send your complete payment card number.

Approved refunds are returned to the original payment method used for the purchase.

After a refund is issued, your bank or payment provider may require additional time to post the amount to your account. Currency conversion differences and third-party transaction fees may not be refundable.
