Payment & Security

Available payment methods are displayed during checkout. We do not ask customers to send complete card numbers by email or telephone.

Authorization and charges

Submitting an order authorizes the selected payment provider to validate and process the transaction. An order is not accepted until payment is authorized and we send an order confirmation. We may decline or cancel an order for failed authorization, suspected fraud, pricing error, inventory unavailability, or legal compliance.

Currency and tax

Prices are displayed in U.S. dollars. Any shipping charge and legally applicable sales tax will be shown before the order is submitted when configured for the delivery destination.

Security

Checkout traffic is protected with HTTPS. Payment credentials are handled through the payment method made available at checkout; TREVONEXA does not intentionally store complete payment-card numbers on this website.
