GNC Coupons

How to apply your GNC coupon

1. Go to gnc.com and add the item/s you wish to purchase to your shopping cart.

2. Pick product customizations, e.g. flavors, serving size, buying options, and then click Add to Cart.

3. Click "View Cart and Checkout" and locate the "Add Promo Code" box on the top right corner of the screen.

4. Paste the GNC promo code into the box and hit "Submit" to apply the savings to your order.

If your coupon is not working, try this:

• Is your discount code invalid due to its expiration date?

• Does the deal come with minimum eligibility requirements as indicated in the "More Details" section?

• Is your code typed or pasted incorrectly or incompletely?

• Are you entering the voucher in the proper letter-case format, e.g. uppercase or lowercase?

If no coupons are available...

You can take advantage of the referral program to get online store credit for every successful referral. Another great way to save is by enrolling in the special discount program to get exclusive savings on your next purchase. Lastly, you can check GNC's Offer Details page to find all active in-store and online promos.

Combining coupons

GNC prohibits combining coupons on your purchases. You can only use one promo code per valid transaction. You can, however, combine different ways to save. For instance, you can use a voucher on an order that qualifies for cash back or free shipping.

Using online coupons in stores

While there are no GNC online coupons for in-store use, there are in-store promos posted on their Offer Details page. Deals include 10% off or more on select products at participating stores.

Most commonly found coupons

While we often have a large selection of GNC coupons, most commonly you'll find a coupon for 50% off. These are often a part of a buy one get one deal, where the second item will be half-price when you apply this code.
