I have to give them a low rating because of customer service. I have been ordering vitamins for years and I in error placed an order with a wrong item and immediately contacted them to fix the order and they couldn't do it. Why? It was within minutes. They said I had to keep it or send it back which cost me shipping charges. I have been ordering online for years and most companies have a grace period time for you to make changes. That's unacceptable.
