I was at the Sams Club in Liberty, MO today and saw they had 750ml bottles of Macallan Double Cask for $45 [samsclub.com]
. That's $15 less than the next cheapest I've seen at other places. I know this is really specific but I figured I'd post. Actually all of the liquor prices at this particular Sam's were good but this was the best deal.
Even though Sams.com says that item isn't available in the Liberty, MO store it's not true they had a lot of bottles. At least 30.
