While doing a Google search I came across this site: www.mcallans.com

They are apparently a brick and mortar in Northern Scotland (Thurso and Wick), have a decent web site and offer free international shipping.

Not planning on making any purchases, but since I didn't see their name here before, I thought I'd mention them. They do have one tartan, Caithness, that they say can only be purchased through them:



Best regards,

Jake
