Do not order from this company...You will lose your money. They say you only pay shipping for the first bottle, but in fact they charge you for the first two bottles and won't refund your money.
They charge a $10.00 restocking fee. Also when you call customer service, they tell you to order 4 more refills, paying only shipping and then you will get your money back. This is ludicrous. I am out $93.00 because of this.
It is hidden in the terms, which you really don't see until after the fact. Do not bother with them...for your own good.
