Additional information

Secure online payment: any online payment data, such as credit card information, is protected via a Secure Socket Layer connection (SSL), which encrypts data making it impossible for third parties to read messages. All browsers support SSL and indicate when it’s place. This forms a global standard for secure payment via the internet.

Privacy: the personal data that we request from you is only used to process your order as efficiently as possible. We respect and guarantee your privacy. Under no circumstances will personal data be shared to third parties.

We use MasterCard/Visa SecureCode and Verified by Visa to provide secure, easy transactions. The conditions of the relevant card issuer are applicable and Optimum Nutrition is not part of the relationship between you and the card issuer. During the order process you can opt for payment by credit card and once the payment has been authorized, it will get sent to our warehouse for picking and shipping.

Paying via Google Pay is quick and easy. During the order process you select Google Pay and are instantly taken to your Google Pay account to make the payment.

Google Pay as payment method is only available on Android Devices, from a Mac/Windows Device when using Google Chrome as a browser and when an account for Google for payments has been setup.

We follow state laws required to calculate sales tax in your specific state (if applicable). Sales tax is not baked into product pricing. Instead, sales tax will show at check out. Thank you!

However, If you have a PayPal account or GooglePay, you will be able to use these cards by choosing one of those options at checkout. Just make sure that the card is linked to your GooglePay or PayPal account before proceeding through the checkout.
