KOIAUT™ · Checkout Information
Payment & Security
This page explains how available payment methods, order totals, transaction authorization, and checkout security are handled when you place an order through koiaut.com.
Payment Methods
The payment methods currently available for your purchase are displayed during checkout. Options may vary depending on location, currency, device, order details, and payment services enabled when the order is placed. Select one of the methods shown at checkout and follow the applicable instructions.
Payment Authorization & Verification
Orders may be subject to transaction and fraud-prevention review before acceptance or fulfillment. Your bank or payment provider may request authorization, identity or payment verification, decline a transaction, or place a temporary authorization hold. These decisions and hold periods are controlled by the applicable financial institution or payment provider.
Checkout Security
Checkout is processed through Shopify together with applicable payment providers and security measures intended to protect transaction information.
Prices & Final Order Total
Before payment is submitted, checkout displays applicable product prices, shipping charges, discounts, taxes where applicable, and the final order total. Prices are shown in U.S. dollars unless another currency is clearly shown. Review products, quantities, shipping information, discounts, and final total carefully before payment.
Financial-Institution Charges
Your bank or payment provider may apply foreign-exchange, currency-conversion, overdraft, interest, or other charges. These charges are determined and collected by the applicable institution or provider and are not controlled by us.
Discount Codes & Promotions
A discount code must be entered and successfully applied before payment is submitted. Promotions may be subject to expiration dates, product eligibility, minimum-purchase requirements, exclusions, usage limits, availability, or other conditions presented with the offer.
Declined, Pending, or Duplicate Charges
If payment is declined, check billing information and contact your bank or payment provider if necessary. A pending amount may be a temporary authorization rather than a completed charge. If you believe you were charged more than once, contact us with your order number and relevant transaction details. Do not send complete card or banking information by email.
Order Confirmation & Payment Questions
After an order is successfully submitted, a confirmation will normally be sent to the email address provided during checkout. If it is not received, check spam or junk folders and confirm the email address used. For payment questions, contact us with a clear description and your order number where available.
Payment Questions
If you believe a payment was charged incorrectly or have a checkout question, email service@koiaut.com. Please include your order number where available and a clear description of the issue. For your security, do not include complete credit-card or banking information in an email.
