Enter the Rewards Code first.
The iHerb Rewards Program works differently from a standard promo code. When you enter a Rewards Code at checkout (in the “Loyalty Credits” or “Referral” field), it attaches a 5% discount to your cart as a loyalty reward — without conflicting with most official promotions.
This is the baseline discount that stacks on top of any promotional code you apply in Step 2. Think of it as your foundation layer.
How to apply: Checkout → Loyalty Programs → Enter Code
Apply a Promo Code. iHerb picks the best one.
iHerb uses a "best discount wins" logic at checkout. Enter any official promo code and the system will apply whichever discount is larger — the code or any existing sale price. The Rewards Code from Step 1 layers independently on top.
