Yes, that is the new "heavy cardboard" box with the latch on it. I saw them side by side recently and the store owner verified the new one. Indeed, grab it for that price. I still run across a few that are not marked up yet. It seems unfair to charge the new price for the old tube. I thought the box was going to be the wooden one like the 25 has, but was mildly disappointed by the one released. The contents are whats important, and I assume that hasn't changed. I stocked up when I heard about the increase, so it will be awhile before I find out. I did find the new Balvenie 17yo New Wood that same day so all is good.
Anyone seen it in quantity yet? They just had the one bottle I bought in stock and being a limited release, I'd like to have a backup if it turns out nice (as yet unopened).
