Available payment methods will be displayed during checkout.

Depending on availability, customers may be able to pay using:

• PayPal

• Major debit cards

The payment methods available to you may vary depending on your location, payment provider, card issuer, or other checkout conditions.

2. Paying with PayPal

If you select PayPal during checkout, you will be directed to PayPal's secure payment environment to complete your transaction.

Depending on the options made available by PayPal, you may be able to complete your purchase by:

• Signing in to your PayPal account, or
• Using an eligible debit or credit card through PayPal without signing in to a PayPal account

Payment information submitted through PayPal is processed through PayPal's payment system.

Trevqina™ does not control PayPal's independent payment authorization procedures, account requirements, or eligibility decisions.

3. Paying by Credit or Debit Card

We accept eligible major credit and debit cards when those payment methods are displayed at checkout.

Available card brands and payment options will be shown during the checkout process.

Card payments are processed through our authorized payment service providers.

Trevqina™ does not directly collect or store your complete credit or debit card information on our own systems.

Your payment information is submitted through the applicable payment provider's secure checkout process.

4. Payment Authorization

All orders are subject to successful payment authorization.

A payment may be declined for reasons including:

• Incorrect billing information
• Insufficient funds
• Card issuer restrictions
• Payment provider security checks
• An expired or invalid payment method
• Other authorization requirements imposed by your bank or payment provider

If your payment is declined, please confirm that your billing and payment information is correct.

For questions regarding card authorization, payment approval, account restrictions, or a declined transaction, you may need to contact your bank, card issuer, or payment provider directly.

5. Payment Security

Protecting customer payment information is important to us.

Payments made through Trevqina™ are processed using secure checkout technology and authorized third-party payment service providers.

Sensitive payment information is handled by the applicable payment processor according to its own security procedures and policies.

We recommend that customers complete purchases only through the official Trevqina™ website and avoid sending complete payment card details through email, text message, or other unsecured communication channels.

6. Currency

All product prices and payments on Trevqina™ are processed in:

United States Dollars (USD)

If your bank account or payment method uses another currency, your bank, card issuer, or payment provider may convert the transaction into your local currency.

Any applicable currency conversion rate or foreign transaction fee is determined by your financial institution or payment provider and is outside Trevqina™'s control.

7. Billing Information

Customers are responsible for providing accurate billing information during checkout.

Please make sure that information such as your:

• Name
• Billing address
• Postal code
• Card information
• Other requested payment details

matches the information associated with your payment method where required.

Incorrect or incomplete billing information may result in a payment being declined or an order being delayed.

8. Payment Confirmation

After a payment is successfully submitted, you should receive an order confirmation using the contact information provided during checkout.

An order confirmation does not necessarily mean that an order has already been shipped.

Orders remain subject to payment verification, order processing, inventory availability, and the terms described in our applicable store policies.

9. Payment Issues

If you believe you have experienced a payment-related issue, please contact us at:

service@trevqina.com

Where a refund is approved under our Return & Refund Policy, the refund will be issued to the original payment method.

Approved refunds are issued within 5–10 business days after the returned item has been received and inspected.

After a refund has been issued, additional time may be required for your bank, card issuer, PayPal, or other payment provider to make the funds available in your account.

Processing times after issuance are determined by the applicable financial institution or payment provider.
