That's right, there are discounts. For example, on this page , you can find discounts on iHerb products across various categories, on the entire purchase, on your first purchase, and so on. This is very convenient, especially when placing a large order. Plus, you'll get free shipping (but check the shipping terms for your country). Overall, it's convenient to use promo codes, get your favorite products at a discount, or try new ones. I use this service often and recommend it to everyone I know.
