It looks like if you buy 2 or more, the discount is included. In the past, it was not but since a few months ago, the discount is included. In other words, the prices of 2 or more are the same as discounted price in the past. So get at least 2.
That's what Frank announced ..about the end of NOV. He said that he was slashing the price to the bone. He said that the one bottle purchase had the big shipping penalty ..but gave the savings to the 2+ bottle purchaser. I think the 1 bottle price went up a small amount, but everything above that was cheaper. When I looked at his new schedule, it appeared to move the higher volume discount down further. That is, the 2 bottle buyer got it at the old 4 bottle price ..the 4 bottle buyer got it at the 8 bottle price ..3/6 ..etc..etc.
