Sorry about this...
We can't actually ship Glenrothes 21 Year Old 1998 (cask 13522) - Xtra Old Particular (Douglas Laing) 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 🙂
