Onnit — frequently asked
How can I get free shipping on my Onnit order?
Onnit offers free shipping on orders over $100 within the contiguous US. Simply fill your cart with $100 worth of your favorite supplements, foods, or gear (excluding fitness equipment and digital items), and you'll automatically qualify for free shipping. It's an easy way to save on your wellness journey!
What is Onnit's return policy?
Onnit stands behind their products with their Keep-It™ guarantee. For first-time purchases of single-serving supplements, you have 90 days to try the product. If you're not satisfied, you can keep it and still get a refund! For other items, they offer a 90-day return window from the date of purchase. Always check their website for the most up-to-date policy details.
Does Onnit offer student discounts?
While Onnit doesn't currently have a specific student discount program, they offer plenty of other ways to save. Keep an eye out for newsletter sign-up bonuses, refer-a-friend programs, and seasonal sales. Don't forget to check their "Sale + More" section for ongoing deals on brain-boosting supplements and fitness gear.
How does the Onnit X rewards program work?
The Onnit X rewards program lets you earn points on every purchase. These points can be redeemed for discounts on future orders or free gifts. As you earn more points, you'll unlock different tiers with increasing benefits. It's free to join and a great way to make your Onnit purchases work harder for you.
Can I use multiple Onnit coupon codes on one order?
Generally, Onnit allows only one coupon code per order. However, you can still maximize your savings! Look for bundle deals, shop during sales events, or sign up for their Autoship & Save program for a guaranteed 15% off. Combine these offers with free shipping on orders over $100 for the best overall value.
What is Onnit's Autoship & Save program?
Onnit's Autoship & Save program offers a 15% discount on recurring deliveries of your favorite products. You can customize your delivery schedule, change or cancel your subscription anytime, and your payment method is only charged right before shipment. It's a hassle-free way to ensure you never run out of your go-to supplements while saving money!
Does Onnit offer military discounts?
