Sorry about this...
We can't actually ship Miltonduff 33 Year Old 1983 (cask 7451) (Adelphi) to the United States at the moment (although we're working hard to fix that).
In the meantime, our friends over at The Whisky Shop might be able to help you out.
Thank you for your support and understanding 🙂
