Review your total before paying
Transactions at ouiavna.com are processed in United States Dollars (USD). Before submitting payment, review the product prices, discounts, applicable delivery charges, taxes, and final total shown at checkout. Currency-conversion charges, foreign-exchange fees, or bank fees are set by your financial institution, not by OuiavNa™.
Choose from the methods shown
The checkout displays the payment methods available for your particular order and location. Depending on the services enabled, these may include major credit cards, debit cards, PayPal, or other supported options.
Authorization and verification
Orders can undergo payment verification and fraud-prevention checks. Your card issuer or payment provider may request verification, decline a transaction, or place a temporary authorization hold. Its approval decision, verification requirements, hold duration, and release schedule are outside our control.
Protecting the payment process
Shopify and participating payment providers process checkout using measures designed to protect transaction information. OuiavNa™ does not keep complete credit- or debit-card numbers on its own systems. No online transmission or storage method is completely secure. Use trusted devices, an up-to-date browser, a secure network, and protected account credentials.
Applying a promotion
Enter discount codes before completing checkout. Offers can have eligibility criteria, expiry dates, exclusions, minimum order values, and other conditions communicated with the promotion. Unless the offer expressly states otherwise, promotions cannot be combined, transferred, exchanged for cash, or applied to a completed order retrospectively.
Help with a payment
Email service@ouiavna.com with your order number, where applicable, if you have a payment question.
