About Coupon Science
We’re obsessed with health! We’ve been buying supplements online about as long as the internet has made it possible. In 2002, we discovered iHerb and began buying almost exclusively from them because of the amazing prices, vast selection, cheap shipping, and amazing service.
In 2009 we started participating in the iHerb Rewards program, and are proud to offer you the latest deals and product recommendations.
At OHC, we are driven by 3 primary objectives:
Share the best health coupons and promo code discounts in the vitamin and supplement space. We proudly support iHerb.
Share original research pieces (we do 1-2 year) on coupon usage in the United States.
Recommend the best and most popular health supplements.
Today, we are primarily focused on vitamin and supplement coupons, promo codes, and discounts, while we also publish new research articles each year.
