“Great product, really like the liquid form. I have been ordering this product for years, have never received a discount code or free shipping. Would be nice for there to be some discounts periodically for loyal customers.”

“Great product, easy to use. My only issue is that Premier has never sent me any discount codes. I have been ordering products from this company for over 10 years and have never received any discounts.”
