Who doesn’t love a good deal? We offer a variety of discount codes to help you save on your Onnit.com order. Here’s everything you need to know to make the most of your coupons:
Using Coupons at Checkout
-
You can apply up to two (2) coupon codes per order during checkout.
This includes:-
Onnit X codes
-
Affiliate codes
-
First responder discounts
-
⚠️ Note: If you enter more than two codes, only the most recent two will apply — new codes will override old ones.
-
Percentage-based discounts do not stack (e.g., two 10% codes will not combine into 20%).
When Coupons Can’t Be Used
Some promotional offers and sale items are excluded from coupon use. If a code isn’t working, double-check if the item is part of a promotion or sale.
Coupon + Point Expiration
-
Coupons expire one year from the date they’re issued.
-
Onnit Points also expire one year after they’re earned.
💡 Use them before they disappear — if you don’t use it, you lose it!
