Payment Information

Payment options

The payment methods available for your specific order are displayed at checkout. Options may vary by order, delivery location, payment provider, or device. Review the available method and order total before submitting payment; we do not list a fixed set of card brands or wallets because availability is determined at checkout.

Currency, shipping, and taxes

Product prices are displayed in U.S. dollars. Shipping choices and charges depend on the order and eligible delivery address; U.S. Standard shipping is free for all eligible orders, with no minimum order total, Order processing generally takes 1–2 business days before dispatch; after carrier acceptance, Standard transit is estimated at 3–6 business days. The transit estimate excludes processing time. Applicable taxes and the final amount due are shown at checkout before you place the order.

Payment issues

If a payment is declined or you have a question about a charge, check the instructions from the payment provider shown during checkout. For help with an order, contact support@protoomega.com with your order number. Order-specific refund eligibility and timing are set out in our Refund Policy.
