They claim that they have a 30 day return policy and that you can return empty bottles. Now let's do the math. 30 days from the date of purchase so let's minus 3 days maybe even 5 for delivery so now you have 25 days to return it. Now you try to follow the policy and call the number and select refund just to be placed on hold for hours so by the time you actually get on the phone with,multiple attempts you are now passed the 30 days which really isn't a full 30days to start with. I should have read the reviews I would have saved myself agrevation and money.
