Payment Methods We Accept
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay and Shop Pay are all supported at checkout. The full list of available options is displayed automatically when you reach the payment step.
Pricing and Currency
All prices are displayed in USD. When your card is issued in a different currency, your bank handles the conversion and may apply its own conversion fee — this is outside our control.
Charge Timing and Confirmation
Payment is collected at the moment you place your order. An order confirmation email is sent to you immediately after the charge is processed.
How We Keep Payments Secure
Every transaction runs through an encrypted SSL/TLS connection handled by PCI-DSS compliant payment providers. GAMMAXIN has no access to and does not store your full card number at any point. Full details are available on our Secure Checkout page.
Declined Transactions and Fraud Review
If your payment is declined, double-check your card details and billing address, or switch to a different payment method. Your bank can provide the specific reason for any decline. To protect our customers, certain orders may be held for review before shipping — we may reach out to verify your information, or cancel and refund any order that appears suspicious.
