Honestly, whenever I’m about to make a big order on iHerb, the first thing I do is check out iHerb coupons.
That site keeps a running list of all the current promo codes and deals, so you don’t have to waste time hunting around. I’ve scored some decent discounts there before, from percentage-off codes to special offers on certain brands. It’s super convenient, especially if your cart is already full — a little extra saving goes a long way. I’d definitely check it out before you hit checkout.
