Unfortunately this can happen sometimes despite careful stock management. If so, you’ll receive an e-mail from our team stating that the product was found to be out of stock. You will receive a refund for any out of stock items that will come back to the card that we have on file for that order. 

Feel free to contact us to discuss your order if you have any additional questions.

Online orders are prepared immediately, so in most cases it is not possible to make any changes after an order has been placed. However, within a 30 - 60 minute time frame we can cancel your complete order and process a refund. Please keep in mind that refunds can take 3-8 business days to process. 

To cancel your order, please call and a customer service agent will be happy to assist. View our opening hours and contact options here.

New York law restricts the sale of dietary supplements marketed for weight loss or muscle building to consumers over the age of 18.  As a result, to ship these products to a New York address, Attended Delivery is required. Attended Delivery requires a person age 21 or older be present to receive the order. If your order contains a qualifying product, Attended Delivery will be selected automatically.

Upon delivery, you must show a valid government-issued photo ID confirming you are 21 years of age or older. An age verification delivery order will be deemed undeliverable if the recipient cannot verify they are 21 years of age or older using a valid government-issued photo ID.

Three total delivery attempts will be made if you are not available the first time. If an Attended Delivery order is deemed to be undeliverable after the above attempts, the entire order will be returned to Optimum Nutrition.
