How to use a GNC code
- Press Get code. That copies the code and opens GNC in a new tab. If you only want the code, use Copy code once it is showing.
- Fill your basket at GNC as normal.
- At checkout, find the promo or discount code box, paste the code and apply it. Check the total actually changed before you pay.
Questions about GNC codes
- How do I use a GNC promo code?
- Press Get code on the code you want. That copies it and opens GNC in a new tab. Fill your basket, then paste the code into the promo code box at checkout and apply it. Check the total actually changed before you pay. If you only want the code, Copy code copies it without opening anything.
- Does GNC have a first-order discount?
- None of the GNC codes we hold are marked as first order or new customer only. That does not rule one out, it just means no code we have states it.
- Why did a GNC code not work?
- Most often the basket does not meet a condition attached to the code, such as a minimum spend or a first-order restriction. Any condition the store stated is shown on the code. Stores can also switch a code off without notice.
- How do I report a code that did not work?
- Open "Details and terms" on that code and answer the "Did this code work?" question. That feedback is what the shopper-confirmed labels on this page are built from.
