Billing Terms & Conditions

Last updated: October 2026

Welcome — this page outlines everything you need to know about how GAMMAXIN handles payments, billing, and any related concerns.

Our Commitment to Transparent Billing

GAMMAXIN is committed to clear, straightforward billing practices. By completing a purchase with us, you acknowledge and agree to the terms described on this page.

Refunds

Approved refunds are returned to your original payment method within 5–10 business days, in accordance with our Return Policy.

Pricing & Taxes

All prices are displayed in USD. Any applicable taxes and shipping fees are calculated and presented to you at checkout, before payment is made.

Authorising Your Payment

When you place an order, you confirm that you are fully authorised to use the payment method provided and that you consent to the total order amount being charged.

Cancelled Orders

Orders cancelled prior to shipment are refunded in full. For orders that have already been dispatched, our standard return process applies.

Resolving Billing Errors

Should you notice any discrepancy in a charge, please reach out to us promptly at Contact@GAMMAXIN.Store. We will review the matter and resolve any confirmed error as quickly as possible.

Chargebacks & Payment Disputes

If a charge appears incorrect, we encourage you to contact us directly at Contact@GAMMAXIN.Store before initiating a dispute through your bank. Most concerns are resolved more efficiently this way, and opening a chargeback without first contacting us may slow down the resolution process.

Updates to These Terms

These Billing Terms may be revised at any time. The most current version will always be available on this page.
