Sorry about this...
We can't actually ship North Port Brechin 40 Year Old 1976 (cask 3887) - Cask Strength Collection Rare Reserve (Signatory) 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 🙂
