iHerb Referral Program
iHerb is an ecommerce store that specializes and sells natural and organic products ranging from health to beauty. They have a wide variety of supplements, makeup, and even cleaning products. They have also expanded to pet and grocery products as well.
They do offer a reward program, but the kicker is you share a link to the last product with your friends rather than the business itself. So technically you’re referring a specific product over the business. But, they do offer a double-sided reward, so it’s not all that bad.
